Astudent wishes to determine the heat capacity of a coffee-cup calorimeter. after she mixes 94.8 g of water at 60.4°c with 94.8 g of water, already in the calorimeter, at 22.3°c, the final temperature of the water is 35.0°c. calculate the heat capacity of the calorimeter in j/k. use 4.184 j/g°c as the specific heat of water. enter to 1 decimal place.

JC⁻¹

Explanation:

= mass of water added to calorimeter = 94.8 g

= initial temperature of the water added = 60.4 C

= specific heat of water = 4.184 Jg⁻¹C⁻¹

= mass of water available to calorimeter = 94.8 g

= initial temperature of the water in calorimeter = 22.3 C

= final equilibrium temperature = 35 C

= Heat gained by calorimeter

Using conservation of heat

Heat gained by calorimeter = Heat lost by water added - heat gained by water in calorimeter

J

= Change in temperature of calorimeter

Change in temperature of calorimeter is given as

C

Heat capacity of calorimeter is given as

JC⁻¹

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
