What is the relationship between energy and temperature change?
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
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.
A graph that shows the change in the temperature of a substance as it is heated will show?
A graph showing the change in temperature of a substance as it is heated will typically show an initial increase in temperature as heat is added, followed by a plateau where the substance changes phase (e.g., from solid to liquid), and then another increase in temperature. The specific shape of the graph will depend on the properties of the substance being heated.
What is the difference between latent heat and specific heat, and how do they affect the temperature changes of a substance?
Latent heat is the energy required to change the state of a substance without changing its temperature, while specific heat is the amount of energy needed to change the temperature of a substance by one degree Celsius. Latent heat affects phase changes (like melting or boiling) while specific heat affects temperature changes. Both play a role in determining how quickly a substance's temperature changes when heat is added or removed.
How will the substance change if energy is added to the liquid at 20 degrees celsius?
Adding energy to a liquid at 20 degrees Celsius will increase its temperature, causing it to heat up. As it reaches its boiling point, the liquid will undergo a phase change and turn into a gas.
The specific heat of substance A is greater than that for substance B If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these s?
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
The size of a temperature increase in a substance depends primarily on?
The size of a temperature increase in a substance primarily depends on the amount of heat energy added to the substance and its specific heat capacity. The specific heat capacity determines how much energy is needed to raise the temperature of a substance by a certain amount.
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.

How could you determine the specific heat of a sample of a solid substance that does not react with water?
One way to determine the specific heat of a solid substance that does not react with water is by using the method of calorimetry. This involves measuring the temperature change of the substance when it is heated or cooled, and using the formula q = mcΔT to calculate its specific heat capacity, where q is the heat added or lost, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change.

What is being added or removed when a substance's temperature changes?
