Answer: Q = 40.8 Kilocalories
Calculations:
We are given the following parameters :
• Mass = 2.55kg = 2.55*1000= 2550
,
• T1 = 21°C
,
• T2 = 37°C
,
• Specific heat of water = c = 1cal/g°C
We will calculate q (heat ) as follows :
[tex]\begin{gathered} Q\text{ = m }\cdot c\cdot\Delta T \\ \text{ = 255}0\cdot\text{ }1\cdot\text{ ( 37-21)} \\ \text{ =}2550\cdot\text{ 16} \\ \text{ = 40800 calories }\ldots\ldots(\text{divide by 1000 to get to kilicalories) } \\ \text{ =40.8 kilocalories } \end{gathered}[/tex]
