Answer 1

Answer:

Heat capacity indicates the amount of energy (heat) necessary to supply to a unit of mass (grams in this case), to increase its temperature by 1 degree (celcius in this case).

If a material has an heat capacity of 3 calories/gram/º Celcius, it means you need

30 calories to increase 10ºCelcius, the temperature of 1 gram of material

or

30 calories to increase 1ºCelcius, the temperature of 10 grams of material

or

30 calories to increase 2ºCelcius, the temperature of 5 grams of material

or

30 calories to increase 5ºCelcius, the temperature of 2 grams of material
