How many degrees will the temperature of water weighing 10 kg change if the entire amount of heat released during

How many degrees will the temperature of water weighing 10 kg change if the entire amount of heat released during the combustion of 0.001 kg of natural gas is transferred to it?

Let’s write down the formulas for the calculation:
1) the amount of heat obtained by burning gas: Qr = mr * qr;
2) the amount of heat received by water: Qb = mw * sv * tv
These two values are equal, we get the equation: 44000 = 42000tB
tB = 0.1 ° C
Answer: 0.1 ° C
