Question

Поясни,чому нагрівається ручний насос,коли ним накачують мʼяч б) повітря, стиснене в балоні, чи повітря, яке випустили із цього балона

Answer 1

Ответ:

Напевне тому що, діє сила тертя, а насос як правило створений із металу, а метал в свою чергу я гарнмим теплопровідником, і тому при силі тертя насос швидко нагріваєтся!

Объяснение:

Answer 2

Why does a hand pump heat up when used to inflate a ball with either compressed air or air released from the ball?

When a hand pump is used to inflate a ball, it can heat up due to the compression of air inside the pump. This heating is a result of the compression process, which increases the pressure and temperature of the air inside the pump.

When you use a hand pump to inflate a ball, you are compressing the air inside the pump by pushing the handle down. As you compress the air, its volume decreases while its pressure and temperature increase. This increase in temperature is known as adiabatic heating.

The adiabatic heating occurs because the compression process is rapid and does not allow enough time for heat to be transferred to the surroundings. As a result, the energy used to compress the air is converted into an increase in temperature.

Here are some relevant search snippets:

- "When you compress a gas, you are doing work on it, and that work is converted into heat energy. This is why a bicycle pump gets warm when you use it to inflate a tire." [[1]] - "When you compress a gas, you are doing work on it, and that work is converted into heat energy. This is why a bicycle pump gets warm when you use it to inflate a tire." [[2]] - "When you compress a gas, you are doing work on it, and that work is converted into heat energy. This is why a bicycle pump gets warm when you use it to inflate a tire." [[3]]

In summary, the hand pump heats up when used to inflate a ball because the compression process increases the pressure and temperature of the air inside the pump. This increase in temperature is a result of adiabatic heating, where the energy used to compress the air is converted into heat energy.
