Calorimetry

Front

What is calorimetry?

Back

Calorimetry is the science of measuring the heat of chemical reactions or physical changes, as well as heat capacity.

Front

What is the principle of heat transfer?

Back

Heat flows from a warmer object to a cooler object until they reach thermal equilibrium (equal temperature).

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1 °C.

Front

How do you calculate heat transfer?

Back

Heat transfer (Q) can be calculated using the formula Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature.

What happens to ice in a drink?

Back

The ice absorbs heat from the drink, causing it to melt.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other because they are at the same temperature.

What is the specific heat of water?

Back

The specific heat of water is 4,186 J/kg∙°C.

Front

How much heat is required to raise the temperature of 1 kg of water by 1 °C?

Back

It requires 4,186 J of heat to raise the temperature of 1 kg of water by 1 °C.

Front

What is the formula for calculating the change in temperature?

Back

The change in temperature (ΔT) can be calculated using the formula ΔT = Q / (mc), where Q is heat transfer, m is mass, and c is specific heat capacity.

What is the heat of fusion?

Back

The heat of fusion is the amount of heat required to convert a unit mass of a solid into a liquid at constant temperature.
