Question

M=2кгQ=50400ДжC=4200Дж/кг °Сt=?​

Answer 1

Ответ:

t=Q/cm=50400/(2×4200)=6°C

Answer 2

To solve for the temperature change (t), we can use the formula:

Q = M * C * t

Where: Q is the heat energy (50400 J), M is the mass (2 kg), C is the specific heat capacity (4200 J/kg °C), and t is the temperature change we want to find.

Rearranging the formula, we have:

t = Q / (M * C)

Substituting the given values:

t = 50400 J / (2 kg * 4200 J/kg °C)

Simplifying the expression:

t = 50400 J / (8400 J/°C)

t = 6 °C

Therefore, the temperature change (t) is 6 °C.
