A difference in this results in different ending temperatures when the same amount of thermal energy is added to two different substances?
The specific heat capacity of a substance determines how much thermal energy is needed to raise its temperature. Therefore, substances with different specific heat capacities will reach different ending temperatures when the same amount of thermal energy is added. Substances with higher specific heat capacities will have smaller temperature increases compared to substances with lower specific heat capacities.
Can heat transfer occur when two substances are the same temperature?
No, heat transfer occurs due to a temperature difference between two substances. If both substances are at the same temperature, there is no temperature gradient to drive heat transfer, so no heat transfer will occur.
A difference in the results in different ending temperatures when the same amount of thermal energy is added to two different substances is called what?
That difference is called specific heat capacity. Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount, so substances with different specific heat capacities will experience different temperature changes when the same amount of thermal energy is added.
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
Different substances have different specific heat capacities, which indicate how much heat energy is required to raise the temperature of a unit mass of the substance by one degree Celsius. Substances with lower specific heat capacities require less heat energy to increase their temperature compared to substances with higher specific heat capacities. Therefore, when the same amount of heat is supplied, substances with higher specific heat capacities will experience less of an increase in temperature compared to substances with lower specific heat capacities.
When the same quantity of heat is added per unit as does a substance having a lower specific heat warm more or less than a substance having a higher specific heat?
A substance with a lower specific heat will warm more than a substance with a higher specific heat when the same quantity of heat is added. This is because substances with lower specific heat require less energy to increase their temperature compared to substances with higher specific heat.
What substance will increase the most in temperature 100G?
Substances with a low specific heat capacity will experience the greatest increase in temperature when 100g of heat is added. This means that metals like copper or aluminum, which have low specific heat capacities, will increase in temperature the most compared to substances like water or sand which have higher specific heat capacities.
Suppose a fixed number of joules of energy as heat is added to 1 kg of substances listed below. Which substance will the rise in temperature be the least?
The substance with the highest specific heat capacity will experience the smallest rise in temperature with the same amount of heat energy added. Water has the highest specific heat capacity among common substances, so it will experience the least rise in temperature when a fixed amount of energy is added.

Why wouldn't the temperature of a substance change when heated or cooled?
There are two points for most substances where a phase change takes place. The energy used to rearrange molecules, called the heat of entropy, must be added or removed before the phase can change. The substances show little or no temperature change at some point in this process.
Do all substances change when heat is added?
yes but only if you heat it enough
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
Different substances have different specific heat capacities, which indicate how much heat energy is required to raise the temperature of a unit mass of the substance by one degree Celsius. Substances with lower specific heat capacities require less heat energy to increase their temperature compared to substances with higher specific heat capacities. Therefore, when the same amount of heat is supplied, substances with higher specific heat capacities will experience less of an increase in temperature compared to substances with lower specific heat capacities.
When two substances come into contact with each other the substance will transfer heat to the substance?
When two substances come into contact, heat will flow from the substance with higher temperature to the substance with lower temperature. This transfer of heat will continue until thermal equilibrium is reached, where both substances have the same temperature.
When the same quantity of heat is added per unit as does a substance having a lower specific heat warm more or less than a substance having a higher specific heat?
A substance with a lower specific heat will warm more than a substance with a higher specific heat when the same quantity of heat is added. This is because substances with lower specific heat require less energy to increase their temperature compared to substances with higher specific heat.
Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
Yes, the greater the difference in temperature between two substances, the faster heat transfer will occur between them. This is because heat naturally flows from areas of high temperature to areas of low temperature in an attempt to reach equilibrium.
Energy that transfers between substances because of a temperature difference between the substances is known as .?
Heat.
