You drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. the ice cube initially has a mass of 60.0 g and a temperature of 0°c. the water (before the ice cube is added) has a mass of 760 g and an initial temperature of 20.0°c. what is the final temperature (in °c) of the mixture? (assume no energy is lost to the walls of the flask, or to the environment.)

Explanation:

Given

Mass of ice

mass of water

Initial Temperature of water

Let T be the Final Temperature of mixture

Latent heat of Fusion

heat required to melt ice completely is

Heat released by water is taken by ice thus

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
