Thermochemistry Review

Front

What is thermochemistry?

Back

Thermochemistry is the study of the heat energy associated with chemical reactions and changes of state.

Front

What is specific heat?

Back

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

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, usually resulting in a temperature decrease.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, usually resulting in a temperature increase.

Front

Which substance heats up fastest: Basalt, Iron, Liquid Water, or Lead?

Back

Lead heats up fastest due to its low specific heat capacity.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is @@6 ext{CO}_2 + 6 ext{H}_2 ext{O} + ext{Energy} ightarrow ext{C}_6 ext{H}_{12} ext{O}_6 + 6 ext{O}_2@@.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is the calorimetry method used for?

Back

Calorimetry is used to measure the amount of heat absorbed or released during a chemical reaction.

Front

What does it mean if a reaction feels cold to the touch?

Back

If a reaction feels cold, it is likely an endothermic reaction, absorbing heat from the surroundings.
