Question

На какую высоту можно было бы поднять гирю массой 1 кг за счет той энергии, которая выделится при охлаждении 250 мл воды от 100 до 0 градусов?

Answer 1

Q=cm(t2-t1)=4200*0.25*100=105кДж

Q=A=FS

S=Q/F=105*10^3/1*10=10500м=10,5км

Calculating the Height to Which a 1kg Weight Could Be Lifted

To calculate the height to which a 1kg weight could be lifted using the energy released from cooling 250ml of water from 100 to 0 degrees Celsius, we can use the formula:

Potential energy = mass * gravity * height

The energy released from cooling the water can be calculated using the specific heat capacity of water and the temperature change.

The specific heat capacity of water is approximately 4.18 J/g°C.

The energy released can be calculated using the formula:

Energy = mass * specific heat capacity * temperature change

Let's calculate the energy released and then use it to find the potential height to which the 1kg weight could be lifted.

The energy released from cooling 250ml (or 250g) of water from 100 to 0 degrees Celsius can be calculated as follows:

Energy = mass * specific heat capacity * temperature change Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C Energy = 250g * 4.18 J/g°C * 100°C **Energy = 250g * 4.18 J
