Question

На скільки градусів має охолонути цегляна піч масою 1,5 т, щоб нагріти повітря в кімнаті об'ємом 50м³ від 8°С до 18°С? ​

Answer 1

Calculating Heat Required to Warm a Room Using a Brick Stove

To calculate the heat required to warm the room, we can use the formula:

Q = mcΔT

Where: - Q = heat energy required (in joules) - m = mass of the air (in kg) - c = specific heat capacity of air (in J/kg°C) - ΔT = change in temperature (in °C)

First, we need to calculate the mass of the air in the room. The density of air at standard conditions (0°C and 1 atm) is approximately 1.225 kg/m³. Given the room volume of 50m³, we can calculate the mass of the air using the formula:

m = ρV

Where: - m = mass of the air - ρ = density of air - V = volume of the room

Let's proceed with the calculations.
