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:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
