1. Heat transfer and specific heat. When a substance absorbs or releases heat the temperature will change. How much the temperature changes will depend on the amount and type of substance and its specific heat, c, which is defined as the amount of energy required to raise the temperature of 1 g of substance 1 °C. Sand has a much lower specific heat compared to that of water, 0.84 J/g °C vs. 4.184 J/g °C. In your group, think about what this means. Which will heat up and cool down faster? Slower? Have you observed this in your life experiences?

the specific heat (cp or cv) can also be understood as a "capacity or ability of a given material to store "heat". In this way, we can say that: 1- the greater the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material.2- the higher the specific heat, the lower the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material3- the lower the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material4- the lower the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change5-the higher the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change choose only one of the above alternatives as correct
