Question

Помогите пожалуйста готовлюсь к кр по физике 3 номера решил, а 4 и не могу. Стальную и свинцовую гири массой 1 кг прогрели в кипящец воде, а затем поставили на лед. Под какой из гирь растает больше льда?

Answer 1

Под стальной, т.к. удельная теплоёмкость стали больше, чем у свинца.

Answer 2

Heating Steel and Lead Weights in Boiling Water

When steel and lead weights with a mass of 1 kg each are heated in boiling water and then placed on ice, the lead weight will melt more ice than the steel weight. This is because lead has a lower specific heat capacity compared to steel, which means it can transfer more heat to the ice and melt more of it.

The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit mass of the substance by one degree Celsius. Substances with lower specific heat capacities can transfer more heat to their surroundings compared to substances with higher specific heat capacities.

Lead has a lower specific heat capacity than steel, which means it can transfer more heat to the ice and cause more melting compared to steel when both are placed on ice after being heated in boiling water.
