If 175 grams of liquid water is heated from 15 degrees C to 35 degrees C, how much energy is absorbed?

14,700 joules

Explanation:

We are given;

Mass of water as 175 g Initial temperature of water as 15°C Final temperature of water as 35°C

We are required to determine the amount of energy absorbed

We need to know that;

Heat energy absorbed is given by the formula;

Heat = Mass * change in temperature * Specific heat

In this case;

Change in temperature = 35°C - 15°C

= 20 °C

Specific heat of water is 4.2 J/g°C

Therefore;

Heat = 175 g * 20°C * 4.2 J/g°C

= 14,700 joules

Therefore, the amount of heat absorbed is 14,700 joules
