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;

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

the answer is 1 i believe

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
