Answer:

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
