The thermal transfer of energy through a copper rod involves electrons. A second process is also involved.

Answers

Answer 1

Answer:

hello your question is incomplete attached below is the complete question

answer : Conduction, Lattice vibration ( B )

Explanation:

The thermal transfer of energy occurs in a solid like a copper rod following two process therefore the second process and method are

Lattice vibration and conduction

Lattice vibration is the movement/oscillation of atoms in a solid and this is caused by the change/increase in temperature applied to the solid and these vibrations will lead to the thermal transfer of energy via conduction since the atoms are bounded together .

The energy transferred to the water in 100 seconds was 155 000 J. specific heat capacity of water = 4200 J/kg °C
Determine the mass of water in the kettle.
Use Figure 10.
Give your answer to 2 significant figures.
Any help would be appreciated

Answers

Answer:

0.37 kg

Explanation:

I'm not a professor myself, but this is how I worked it out:

using the graph, after 100 seconds, the temperature is 100 degrees Celsius.

If we now substitute everything into the specific heat capacity equation, making the mass "m", we would come up with:

4200 = 155000/(m x 100)

If we rearrange and solve for m, we get 0.37 kg.

I'm not sure if I have done this correctly, feel free to correct me.

Hope this helps!

By using the specific heat capacity formula, the mass of water in the kettle is 0.47 kg

Give that the energy transferred to the water in 100 seconds was 155 000 J and the specific heat capacity of water = 4200 J/kg °C

From the graph;

The initial temperature of the water at time zero is 22 degree Celsius

The final temperature of the water at time 100s is 100 degree Celsius

Change in temperature (T) = 100 - 22 = 78 degree Celsius

To determine the mass of water in the kettle, use the heat energy formula below

E = mcT

Substitute all the parameters into the equation

155000 = 4200 x 78 M

Make M the subject of the formula

M = 155000/327600

M = 0.47 kg

Therefore, the mass of water in the kettle is 0.47 kg

I think this bcuz it says it should be useful and comfortable and so four is correct bcuz they need to know if it feels good and also if it possibly would give a rash or worse. Next, all the other ones would prove how well the suits work in the conditions need for use.

Hope this helps.

All of the above, because not only does the suit need to be fire safe but it also has to be comfortable for the fireman to perform their very best. They would have to consider how each material might carry and hold smoke and withstand fires so that the materials not only block the fireman from getting burnt, but also prevent them from getting too overheated because you don’t want to make the suits too thick to the point that the fire mixed with the suit will make them too exhausted or heavy. When there’s an immediate emergency, you need to consider which materials might be lighter because it’s hard to move quick with heavy uniforms

An 80 kg runner has 3,000 J of kinetic energy. What is her velocity in m/s?

Answers

Answer: 8.6m/s

Explanation:From KE=1/2mv^2

In order to make v the subject of the formula we divide both sides by 1/2m. Thus V^2 will be left alone on the RHS. But we are looking for v and not v^2. Thus we find the square root of KE1/2m

Meaning V= sqrt[3000÷1/2 of 80]

=sqrt[3000÷40]

=sqrt(75)

=8.6m/s

The mass of an object is 84 kg. Find its weight on the Earth and the Moon.

Answers

Answer:

We would take the mass given, 80 kg, and multiply it times the acceleration of Earth's downward pull on that mass, 9.8 m/s/s. So the weight on Earth is 784 newtons. So the weight of the same 80 kg mass on the moon is 133.28 N.

mass is express in Newtons.

On Earth gravity is 9.807 so wieght would be : 9.807 * 84= 823.79

On the Moon garvity is 1.62 so weight would be : 84 *1.62 = 136.08

Covalent compounds are characterized by bonding that involves sharing electrons.

Covalent compounds have the ability to share electrons as they mostly have 4 valence electrons.

What are covalent compounds?

Covalent compounds are defined as type of compounds which are formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent compounds have bonding which involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.
