Question

Describe in detail an experiment using only hot and cold water that would enable you to

Answer 1

Based on the principle of conservation of energy, the heat capacity of the calorimeter is calculated using the formula:

• c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)

What is a calorimeter?

A calorimeter is an equipment used to determine heat of reaction.

The calorimeter works on the principle of conservation of energy:

• heat gained = heat lost

Quantity of heat energy is calculated using the formula below:

• q = mass × heat capacity × temperature difference

In the experiment, the following procedure is followed:

• Mass of the hot water, cold water and calorimeter are recorded
• temperature of the hot water is recorded
• temperature of the the cold water and calorimeter is recorded
• final temperature of the mixture is recorded
• heat capacity of the calorimeter is calculated using the formula: heat gained by calorimeter and cold water = heat lost by hot water.

Assuming that;

• mass of hot water = m1
• mass of cold water =m2
• mass of calorimeter = m3
• initial temperature cold water and calorimeter = t1
• final temperature of mixture = t2
• heat capacity of water = w
• heat capacity of calorimeter = c

Therefore, the heat capacity of the calorimeter is calculated using the formula:

• c = {m2 × w × (t2 - t1) - m2 × w × (t2 -t1)}/m3 × (t2 -t1)
