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

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
