Calorimetry and Specific Heat

Front

What does a flat section on a temperature-time graph indicate in calorimetry?

Back

Constant temperature, indicating a phase change.

Front

What is the purpose of determining the calibration factor in solution calorimetry?

Back

To account for heat loss to the surroundings.

Front

What is a common method to analyze temperature-time graphs in solution calorimetry?

Back

Determining the initial and final temperatures.

Front

What is the specific heat capacity of aluminum in J/g°C?

Back

0.897 J/g°C.

Front

What type of reaction occurs if a substance releases heat and the temperature of the water increases?

Back

Exothermic reaction.

Front

Define calorimetry.

Back

Calorimetry is the science of measuring the heat of chemical reactions or physical changes.

Front

What is specific heat capacity?

Back

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

Front

What is the formula for calculating heat transfer (q)?

Back

q = m × c × ΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Front

What does an endothermic reaction do?

Back

An endothermic reaction absorbs heat from its surroundings.

Front

What is the specific heat capacity of water in J/g°C?

Back

4.18 J/g°C.
