E = mass x specific heat x Δ°T
Δ°T = new temperature - original temperature
where Δ°T is equal to temperature change (Celsius in this case). The specific heat of Al is 0.900 J/g°C.
Before we proceed to find the quantity of heat in joules, we must first find the temperature change. To calculate the temperature change, we must subtract the original temperature from the new temperature.
Δ°T = 50°C - 25°C = 25°C
In order to find the quantity of heat (joules), we must multiply mass, specific heat, and the temperature change (calculated above).
E = 40.0g x 0.900 J/g°C x 25°C
= 900 Joules or 9.0 x 102 Joules

The specific heat of air at 0 degrees Celsius is 1.01 Joules per gram or J/g. The specific heat of a substance is defined as the quantity of heat per unit mass needed to raise its temperature by one degree Celsius.

The latent heat of condensation of steam is 2260 Joules per gram (539.3 cals/g). So the amount of heat released by 12.4 g = 12.4*2260 Joules = 28,024 Joules or 6687 cals.
Density = grams/ml 1.00 g/ml = X g/5.0 ml = 5.0 grams water ============== q(joules) = mass * specific heat * change in temp. q = (5.0 grams)(4.180 J/gC)(75 C - 2.50 C) = 1515.25 Joules ---------------------------------/4.184 = 362 calories -------------------
