Calorimetry and Heat Transfer

This set of flashcards covers key concepts in calorimetry, including the methods of heat transfer, the function of calorimeters, and related equations.

What is the direction of heat transfer according to the laws of thermodynamics?

Heat is always transferred from higher temperature to lower temperature.

What are the three methods of heat transfer?

Conduction, Convection, and Radiation.

How does conduction transfer heat?

Through direct contact of particles.

What is convection in terms of heat transfer?

Transfer of heat through the movement of heated particles.

What is radiation in terms of heat transfer?

Transfer of heat through emission of electromagnetic waves.

What tool is used to measure energy absorbed or released as heat?

Calorimeter.

In a calorimetry experiment, what does the equation q = mCAT represent?

q represents the heat absorbed or released, m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

What happens to the temperature of H2O when it absorbs heat from a heated sample?

The temperature of H2O increases.

When a heated sample releases heat, what sign is the heat change q associated with?

Negative (-q) for the heated sample.

What is the specific heat capacity of water (H2O)?

4.1890 kJ/kg·K.
