Question

Физика 8 класс какое количество теплоты потребуется отвести от воздуха комнаты с температурой 30 градусов цельсия и объемом 60 метров крадратных, чтобы охладить его до температуры 20 градусов цельсия

Answer 1

Q=m*Cв*Δt , m=рV , m-масса , р-потность воздуха, V- обьем комнаты, Δt=30-20=10, Cв-удельная теплоемкость воздуха

Answer 2

Calculation of Heat Transfer

To calculate the amount of heat required to cool the air in a room from 30 degrees Celsius to 20 degrees Celsius, we need to use the formula:

Q = mcΔT

Where: - Q is the amount of heat transferred - m is the mass of the air - c is the specific heat capacity of air - ΔT is the change in temperature

To find the mass of the air, we need to know the volume of the room and the density of air. However, the volume of the room is given as 60 square meters, which is a two-dimensional measurement. We need the volume in cubic meters to calculate the mass of the air. Unfortunately, the given information does not provide the necessary details to calculate the mass of the air.

Therefore, without the volume of the room or the density of air, it is not possible to determine the exact amount of heat required to cool the air in the room from 30 degrees Celsius to 20 degrees Celsius.
