Question

Для нагревания 1 кг золота на 1 градус требуется 130 Дж. Какова удельная теплоёмкость золота?

Answer 1

Она и будет 130Дж/кг*С )))

Answer 2

Calculating Specific Heat Capacity of Gold

To calculate the specific heat capacity (c) of gold, we can use the formula:

c = Q / (m * ΔT)

Where: - c = specific heat capacity - Q = heat energy - m = mass - ΔT = change in temperature

Given that it takes 130 J to heat 1 kg of gold by 1 degree, we can use this information to calculate the specific heat capacity of gold.

Calculation

Using the formula c = Q / (m * ΔT), we can substitute the given values: - Q = 130 J - m = 1 kg - ΔT = 1 degree

So, c = 130 J / (1 kg * 1 degree)

Result

Calculating the specific heat capacity: c = 130 J / (1 kg * 1 degree) = 130 J / 1 kg = 130 J/kg

Therefore, the specific heat capacity of gold is 130 J/kg.
