Question

В медный калориметр массой 200 г налили 150 г воды при температуре 10(градусов). В этот же калориметр опустили стальной цилиндр нагретый до температуры 100 градусов в результате теплообмена в калориметре установилась температура 20 градусов какова масса цилиндра?

Answer 1

Calculation of the Mass of the Steel Cylinder

To calculate the mass of the steel cylinder, we can use the principle of heat exchange in the calorimeter. The heat gained by the water is equal to the heat lost by the steel cylinder. We can use the equation:

m1 * c1 * (Tf - Ti) = m2 * c2 * (Tf - Ti)

Where: - m1 is the mass of the water (150 g) - c1 is the specific heat capacity of water (4.18 J/g°C) - Ti is the initial temperature of the water (10°C) - m2 is the mass of the steel cylinder (unknown) - c2 is the specific heat capacity of steel (unknown) - Tf is the final temperature of the system (20°C)

We can rearrange the equation to solve for m2:

m2 = (m1 * c1 * (Tf - Ti)) / (c2 * (Tf - Ti))

Now, let's substitute the known values into the equation and solve for m2:

m2 = (150 g * 4.18 J/g°C * (20°C - 10°C)) / (c2 * (20°C - 10°C))

Unfortunately, the specific heat capacity of steel (c2) is not provided in the question. Therefore, we cannot calculate the exact mass of the steel cylinder without this information.

If you have the specific heat capacity of steel, please provide it so that we can proceed with the calculation.
