<em>The heat transfer by conduction occurs due to the collision between the molecules in the substance.</em>

Explanation:

The heat transfer between the substances or in a medium is carried out by means of three methods.

Conduction
Convection
Radiation

The conduction is the process of transfer of heat within the substance by transferring the heat one by one to each molecule throughout the substance by colliding with the neighboring molecule. This method prevails in the transfer of heat in the solids.

The convection is the process of transfer of heat in which the source of heat is used to heat a particular bunch of molecules or a layer of the substance and then that layer moves away from the source and lets other molecule to come close to the layer. This method of heating is used in liquids.

The radiation is the process of transfer of heat in the medium by means of the energy carried by the radiation. This process of heating is used for the heating of the gases in the medium.

Thus, <em>The heat transfer by conduction occurs due to the collision between the molecules in the substance.</em>

Which of the following are true statements? A. Like charges repel B. Unlike charges repel C. Unlike charges attract or D. Charge

Brums [2.3K]

Answer: The correct answers are (A) and (C).

Explanation:

The expression from electrostatic force is as follows;

$F=\frac{kq_{1}q_{1}}{r^{2} }$

Here, F is the electrostatic force, k is constant, r is the distance between the charges and $q_{1},q_{1}$ are the charges.

The electrostatic force follows inverse square law. It is inversely proportional to the square of the distance between the charges. It is directly proportional to the product of the charges.

Like charges repel each other. There is a force of electrostatic repulsion between the like charges. Unlike charges attract each other. There is a force of electrostatic attraction between unlike charges.

The charges are induced on the neutral object when it is placed nearby the charged object without actually touching it.

Therefore, the true statements from the given options are as follows;

Like charges repel.

Unlike charges attract.

Given the following specific heat capacities, which material was have the largest change in temperature if 10 grams of each subs

Ilya [14]

Answer:

Explanation:

Comment

You could calculate it out by assuming the same starting temperature for each substance. (You have to assume that the substances do start at the same temperature anyway).

That's like shooting 12 with 2 dice. It can be done, but aiming for a more common number is a better idea.

Same with this question.

You should just develop a rule. The rule will look like this

The greater the heat capacity the (higher or lower) the change in temperature.

The greater the heat capacity the lower the change in temperature

That's not your question. You want to know which substance will have the greatest temperature change given their heat capacities.

Answer

lead. It has the smallest heat capacity and therefore it's temperature change will be the greatest.
