A heater raises the temperature of air in a room from 22 °C to 37
°C with the energy of 7500 J. If the mass of the air is 5 kg, the specific heat
capacity of the air would be

A. 25 J kg^-1 °C^-1
B. 50 J kg^-1 °C^-1
C. 100 J kg^-1 °C^-1
D. 75 J kg^-1 °C^-1

The specific heat of air is 100  J/kg°C.

Explanation:

mass, m = 5 kg

Temperature change, T' - T =  37 °C - 22 °C = 15°C

heat, H = 7500 J

let the specific heat of air is c.  

The formula of heat is

H = m c (T' - T)

7500 = 5 x c x 15

c = 100 J/kg°C

c

explanation:

i believe the answer is c and this is only worth 10 points you might wanna change it

you have to draw the persons position over there
