Question

Оцените количество теплоты, выделившееся при охлаждении полной ванны воды на 1'C.Объём не известен.

Answer 1

Лохань в 200 литров содержит 200 килограмм воды. Теплоёмкость такой штуки будет C*m = 4200*200 = 840000 Дж на градус.
Значит, при остывании на 1 градус выделится 840 кДж теплоты.

Answer 2

Calculating Heat Released When Cooling Water

To calculate the amount of heat released when cooling a full bath of water by 1°C, we can use the formula:

Q = mcΔT

Where: - Q = heat energy (in joules) - m = mass of the water (in grams or kilograms) - c = specific heat capacity of water (4.18 J/g°C) - ΔT = change in temperature (in °C)

Since the volume of water is not known, we can assume a standard volume for a full bath, which is typically around 150 liters or 150,000 grams.

Using the given formula and assuming a standard volume, we can calculate the heat released when cooling the water by 1°C.

Calculation

Using the formula Q = mcΔT: - m = 150,000 grams (assuming a standard volume for a full bath) - c = 4.18 J/g°C (specific heat capacity of water) - ΔT = 1°C

Plugging these values into the formula: Q = 150,000g * 4.18 J/g°C * 1°C

Result

Q ≈ 627,000 Joules

Therefore, the amount of heat released when cooling a full bath of water by 1°C is approximately 627,000 Joules.
