Temperature is not a direct measure of thermal energy of a system the total energy depends on its temperature and what other factors?
Answers
Answer:
See explanation
Explanation:
There are two main factors that affect the magnitude of thermal energy of a system.
The thermal energy of a system depends on
i) Temperature of the body
ii) Mass of the body
Thus, the greater the mass of a substance at a particular temperature, the greater its thermal energy. Also, at a higher temperature, an object has greater thermal energy.

What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answers
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

Write a scientific explanation that compares the electrical forces of ethanol, hexane, and water.
Claim:
Evidence:
Reasoning:
Answers
Answer:
"Water and ethyl alcohol will both have dipole-dipole interactions.
Technically they will both have Hydrogen bonding, which is a type of dipole-dipole. This is due to the high electronegativity values of oxygen atoms compared to the carbon and hydrogen atoms the oxygens bond to. This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges.
Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces."

Answers
Answer:
1.62 × 10⁻²⁴ J
Explanation:
Step 1: Given and required data
Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.sStep 2: Calculate the energy (E) of this electromagnetic radiation
We will use the Planck-Einstein's relation.
E = h × ν

[tex]\boxed {\boxed {\sf 447,560 \ Joules}}[/tex]
Explanation:
We are asked to find the energy required to melt 1340 grams of ice. We are given this formula:
[tex]Q=mL[/tex]
In this formula, Q is the heat, m is the mass, and L is the latent heat.
For this problem, the mass is 1340 grams of ice. Since we want to melt the ice, we need the latent heat of fusion (melting) which is 334 Joules per gram.
[tex]m= 1340 \ g \\L= 334 \ J/g[/tex]
Substitute the values into the formula.
[tex]Q= (1340 \ g )( 334 \ J/g)[/tex]
Multiply. The grams will cancel each other out.
[tex]Q=1340 *334 \ J \\Q=447560 \ J[/tex]
447,560 Joules of energy are needed to melt 1340 grams of ice.

C3H8 (g) + 5 O2 (g)
->
3 CO2 (g) + 4 H2O (9)
1. Use stoichiometry to determine how many moles of O2 are needed
to completely react with 2.25 moles of C3H8.
Answers
Answer: 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].
Explanation:
The balanced chemical equation is:
[tex]C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)[/tex]
According to stoichiometry :
1 mole of [tex]C_3H_8[/tex] require = 5 moles of [tex]O_2[/tex]
Thus 2.25 moles of [tex]C_3H_8[/tex] will require=[tex]\frac{5}{1}\times 2.25=11.25moles[/tex] of [tex]O_2[/tex]
Thus 11.25 moles of [tex]O_2[/tex] will be required to completely react with 2.25 moles of [tex]C_3H_8[/tex].

Mr. Wang works in a recycling center. Recyclable materials arrive at the
center mixed together. Workers use magnets to separate steel cans from
other items. Which two statements are true about the force between a steel can and a magnet?
1 Gravity pushes the can toward the magnet.
2 The force between the can and the magnet is a noncontact force.
3 The attraction between the can and the magnet is a pull.
4 The attraction between the can and the magnet is a push
Solution
The force exerted by magnet on steel is the pull force. In magnets unlike poles attract each other (pull force) while the like poles repel (push force). Now, the steel or any ferrous object in the garbage when experience magnetic field develop magnetic field of their own in such a way that their north always faces the south of the external magnet or vice versa.
Hence, the force between a steel can and a magnet is pull force
