Exactly 15.5 ml of water at 23.0 °c is added to a hot iron skillet. all of the water is converted to steam at 100.0°c. the mass of the skillet is 1.20 kg. what is the change in temperature of the skillet?

Explanation:

Given:

Volume of water,

initial temperature of water,

final temperature of water before forming steam,

mass of hot skillet,

Usually skillets are made of cast iron and cast iron has a specific heat capacity of :

Specific heat of water,

Latent heat of vaporization of water,

Now, mass of water:

Quantity of heat absorbed by the water of 23 degree Celsius to a point just before steaming:

Quantity of heat absorbed by the water to vapourize:

∴Total heat lost by the skillet:

For change in temperature:

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
