To bring 1.0kg of water from 25cto 99c takes how much heat input?

Heat,

Explanation:

Given that,

Mass of water, m = 1 kg

Initial temperature,

Final temperature,

The specific heat of water is,

The heat released due to the change in temperature is given by :

So, the heat input is . Hence, this is the required solution.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

a electronegativity decreases beacuse the size of nucleus is bigger.
