Question

Щоб нагріти на примусі воду, було витрачено 75 г гасу. Яку кількість теплоти дістала вода, якщо на її нагрівання затрачено 34 відсоткiв тiєï теплоти, що виділилася при згоряннi гасу?

Answer 1

Дано:          СИ:               Решение:

m=75г         0,075кг        Qп=Q-n  

n=34%                              Q=mq                

q=$4,6*10^{7}$Дж/кг             Qп=mq-n          

Qп-?                                 Qп=$0,075*4,6*10^{7}$$-34%$%=1173000Дж

Ответ: Qп=1173кДж

Answer 2

To calculate the amount of heat received by the water, we need to find the total heat released by the combustion of gas and then multiply it by the percentage of heat used to heat the water.

Let's break down the problem step by step:

1. The amount of gas used to heat the water is given as 75 g. 2. The heat released by the combustion of gas is the total heat available. 3. The percentage of heat used to heat the water is given as 34%.

Now, let's calculate the amount of heat received by the water:

1. Find the total heat released by the combustion of gas: - We need to know the heat of combustion of the gas used. Unfortunately, the search results did not provide this information. Without this information, we cannot calculate the total heat released by the combustion of gas.

2. Multiply the total heat released by the percentage of heat used to heat the water: - Once we have the total heat released by the combustion of gas, we can multiply it by 34% to find the amount of heat received by the water.

Unfortunately, without the heat of combustion of the gas, we cannot provide a specific answer to the question. Please provide the heat of combustion of the gas used, and we will be able to calculate the amount of heat received by the water.
