Question

Assume that 50.0 cal of heat is applied to a 15 g sample of sulfur at 20°C. What is the final temperature of the sample if the specific heat of sulfur is 0.175 cal/(g • °C)?

Answer 1

Heat gained or absorbed in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)
50.0 cal = 15 g (0.175 cal/g-C) (T2-T1)
T2-T1 = 19.05 C
T2 = 19.05 + 20
T2 = 39.05 C
