How much energy must be absorbed by 50 grams
of water in order to raise the temperature by
20°C? The specific heat of water is on your
periodic table.



Answer :

Final answer:

Specific heat is the energy required to change the temperature of a substance per unit mass. Use the formula q = m c ΔT to calculate the energy needed to raise the temperature of 50 grams of water by 20°C.


Explanation:

Specific heat is the amount of energy needed to raise the temperature of a substance by one degree Celsius per unit mass. In this case, to calculate the energy needed to raise the temperature of 50 grams of water by 20°C, you use the formula:

q = m c ΔT

where q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. Plug in the values and calculate the result.
