How much energy is required to raise the temperature of 11.4 grams of gaseous helium from 24.2 °C to 38.3 °C?

Q = 835J

Explanation:

Specific heat capacity of Helium=5.193J/gk

Q=msΔT

ΔT=T2-T1

Q=change in energy

m=mass of substance

S = Specific heat capacity

Q = Change in energy

T2 = 38.3 degrees Celsius = (38.3+273) k = 311.3k

T1=24.2 degree Celsius = 24.2+273k

T1=297.2k

ΔT=T2-T1 = (311.3-297.2) k=14.1K

Q = (11.4g) * (5.193J/gk) * (14.1k)

Q=834.72282J

Approximately, Q = 835J
