Answer 1

Answer:1500 calorie

Step-by-step explanation:

Given

volume of water
`V=50\ ml`

Initial temperature
`T_i=22^(\circ)C`

Final temperature
`T_f=52^(\circ)C`

We know,

specific heat of water is
`c=1\ calorie/gm-^(\circ)C`

the density of water is
`\rho=1\ gm/ml`

The heat required to raise the temperature

`\Rightarrow Q=mc\Delta T\\\Rightarrow Q=\rho \cdot V* c* \Delta T\\\Rightarrow Q=1* 50* 1* (52-22)\\\Rightarrow Q=1500\ cal.`

1500 calories is required
