On a cold winter day when the temperature is -20°C, what is the amount of heat needed to warm to 37°C (internal body temperature) the 0.50 L of air exchanged with each breath? Assume that the specific heat capacity of air is 1020 J (kg. Cº) and that 1.0 L of air has a mass of 1.3 g.

the answer is 3.1 his answer is wrong mines is right

i think its c if i'm wrong

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
