Thermal energy is what happens when heat moves between substances.

Thermal energy usually refers to the temperature of an object which indicates the energy it has

Temperature is used as a guide to the level of thermal energy from objects

While heat is the transfer of thermal energy

Heat moves when there is a difference in temperature

The amount of heat is influenced by the mass of the object and the difference in temperature

Can be formulated  :

Q = m.c.ΔT

Q: heat received or removed by an object (J)

m: object mass (kg)

c: heat type substance (J / kg⁰C)

ΔT: temperature change (⁰C)

I dont know why the other one has 5 starts but the answer is They represent different concepts.

Answer:

True.

Explanation:

You didn't provide an answer, but I'm assuming this is a T/F question.

Answer:

Explanation:

GIVEN ; FORCE = 2000 NEWTON

DISPLACEMENT = 10 M

TIME = 50 SECONDS

AS WE KNOW , POWER = WORK / TIME

= WORK = FORCE × DISPLACEMENT = 2000 × 10

= 20000 JOULES

THEN, POWER = 20000/ 50

SO, POWER = 400 WATT ( JOULES / SECOND )

Explanation:

Answer:

atoms of isotopes of an element have different numbers of neutrons.

Explanation:

isotopes have the same number of protons, but different numbers of neutrons.

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Atoms of isotopes of an element have different numbers of neutrons.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

One element can have isotopes of its own. Isotopes are the atoms of element with same atomic number but different mass number. Example Hydrogen has three isotopres like hydrogen, deuterium and tritium with mass number 1, 2 and 3 respectively. Atoms of isotopes of an element have different numbers of neutrons.

Therefore, atoms of isotopes of an element have different numbers of neutrons. The correct option is option B.

Answer:

One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules.

Neon's destiny is to produce vibrant and attractive colors in neon signs, while Mohs hardness is a scale used to measure the hardness of minerals, and it does not apply to the element neon.

Neon's destiny refers to the role or purpose of the element neon in the natural world. Neon is a noble gas that is commonly used in neon signs due to its vibrant red-orange color when electricity is passed through it. Its destiny, in this context, is to create visually appealing and eye-catching signs.

On the other hand, Mohs hardness is a scale that measures the hardness of minerals. It was developed by Friedrich Mohs in 1812. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest mineral.

Now, let's discuss the Mohs hardness of neon. Neon is an element, not a mineral, so it does not have a specific Mohs hardness value. The Mohs hardness scale is specifically designed for minerals, not elements. Therefore, we cannot assign a Mohs hardness value to neon.

According to Gay-Lussac's Law The pressure of the gas increases with increase in temperature of the gas when volume of the gas is kept constant

Explanation:

Answer:

A

Explanation:

The more energy u give the more the electron is able to get far away from the nucleas. So the opposite happens when u take away some energy, it will falll on lower energy state and will radiate the energy difference in form of a photon/light.

Answer:

C

Explanation:

Option C is an accurate model of ethane.

Ethane is an alkane that has two carbon atoms bonded together and each atom has three hydrogen atoms that are attached to them. Ethane has single bonds and that makes it an alkane.

This model of ethane has six carbon-hydrogen bonds shown with solid lines that are protruding out. Rotation that takes place about the carbon-carbon bond actually results in the different molecular conformations of ethane.

Answer:

Electrons on the last energy level.

The period on the periodic table (1 to 7) tells the number of energy levels in an atom. Therefore, option A is correct.

The horizontal rows in the modern periodic table are known as periods. All elements placed in a particular period have an equal number of electron shells. Each next element exceeds one proton in a period and so exhibits less metallic character than its precursor.

The atomic number of the elements increases from left to right in a period that gives information about the number of electrons and protons increases in an atom. As in a period, elements have filled an equal number of electron shells, but an increased electron in the same shell causes an increase in the nuclear charge. Therefore, the atomic radius of an element of the elements reduces in a period.

Therefore, the elements in the same period (1 to 7) have the same number of electron shells or energy levels.

Answer:

The answer is c) moon’s motion without gravity

Explanation:

I just took the quiz and I got 100 percent on Edgenuty :)

The dotted-line arrow is representing the path the moon would take if there was no force of gravity on the earth. Therefore, option (C) is correct.

Gravity can be explained as a force that attracts an object toward the center of the earth or any physical system that has mass. Each body with mass exerts a force or gravity on every other body with mass. Gravity is the force that keeps the moon around the earth and the planets in orbit around the sun.

In the universe, each particle with mass attracts another particle with a definite force, and that force acting is a product of the masses of those bodies.

Mathematically gravity acting between masses can be written as:

[tex]F =G\frac{q_1q_2}{r^2}[/tex]

Where F is the force, m and M are masses, G is the universal gravitational constant and r is the separation between them.

If the moon follows the dotted arrow which moves straight ahead it can be only possible if the moon's motion is without gravity.

Explanation:

Fog forms as an aerosol which is visible to the eye that normally consists of tiny condensed water vapor droplets or crystals of ice that is formed when air that is warm comes in contact with cool air close to the Earth's surface. Fog can be taken as a stratus like cloud that lies close to the Earth's surface and it normally forms due to the presence of water bodies that are nearby, the topography of the area or the conditions of the wind.
