The specific heat capacity of methane gas is 2.20 J/g-K. How many joules of heat are needed to raise the temperature of 5.00 g of methane from 36.0 °C to 75.0 °C?

Question

Quizplus · Accepted Answer

The formula for calculating heat is:
q = m × c × ΔT
where:
q = heat (in J)
m = mass (in g)
c = specific heat capacity (in J/g-K)
ΔT = change in temperature (in K or °C)
Plugging in the given values:
q = 5.00 g × 2.20 J/g-K × (75.0 °C - 36.0 °C)
q = 429 J
Therefore, the answer is B.

The Specific Heat Capacity of Methane Gas Is 2
