12 Questions
What factors determine the quantity of heat required to raise the temperature of a substance?
Specific heat capacity, amount of the substance, and the temperature change
If you raise the temperature of a given quantity of water by 40 °C instead of 20 °C, what change do you observe in the time taken?
The time taken will be about twice as long
How does the time taken to raise the temperature of double the amount of water by 20 °C compare to the time taken for the initial amount of water?
The time taken will be about twice as long
What difference do you observe in the time taken to raise the temperature of oil compared to water by 20 °C?
The time taken for oil will be shorter
How does the motion of water particles change as the temperature is raised?
The motion of water particles increases until it becomes turbulent when boiling
What happens to the quantity of heat required when the amount of water is doubled but the temperature change remains the same?
The quantity of heat required also doubles
Define heat capacity of a substance.
The heat capacity of a substance is the amount of heat required to change its temperature by a certain amount.
What is specific heat capacity of a substance?
The specific heat capacity of a substance is the amount of heat required to change the temperature of unit mass by one unit.
How is specific heat capacity defined?
The specific heat capacity is defined as the amount of heat per unit mass absorbed or rejected by the substance to change its temperature by one unit.
What is the SI unit of specific heat capacity?
The SI unit of specific heat capacity is J kg–1 K–1.
How is molar specific heat capacity defined?
Molar specific heat capacity is defined as the heat capacity per mole of the substance.
What are the two types of molar specific heat capacities for gases?
The two types are molar specific heat capacity at constant pressure (Cp) and molar specific heat capacity at constant volume (Cv).
This quiz explores the concept of specific heat capacity and the process of heating water. Learn about the factors that affect the amount of heat required to raise the temperature of a substance, as well as the behavior of water particles as it is heated.
