HELP FAST WILL MARK BRAINLIEST (for a real answer) An electric heater heats the air an industrial chamber, raising its temperature from 30 degrees Celsius to 180 degrees Celsius. The mass of the air in the chamber is 1,200 kilograms. The specific heat of air is 1,000 J/kg degrees Celsius . How much electrical energy does the heater consume?

A: 12,000 joules

B: 1,80 million joules

C: 1,800 joules

D: 12 million joules

B. 180 million joules

Explanation:

Apply the formula for heat transfer given as;

Q=m*c*Δt  where

Q = electrical energy consumed by the heater in joules

m= mass of air in the chamber in kg

c= specific heat of air in joules per kg degrees Celsius

Δt= change in temperatures in degrees Celsius

Given in the question;

m= 1200 kg

c= 1000 J/°C /kg

Δt = 180°-30°= 150° C

Substitute values in the equation to get Q as;

Q=m*c*Δt

Q= 1200 * 1000* 150

Q= 180000000 joules

Q = 180 million joules

The correct answer option is B : 180 million joules.
