Two 84.5 g ice cubes are dropped into 30 g of water in a glass. if the water is initially at a temperature of 50 c and if the ice comes directly from the freezer at -300 c, what will be temperature of the drink when the ice and the water reach thermal equilibrium ? how much ice and how much water are present at thermal equilibrium ? ignore the heat capacity of the glass and heat transferred to and from the environment.

final temperature will be 0 degree C

Total amount of ice will be

total amount of water

Explanation:

After thermal equilibrium is achieved we can say that

Heat given by water = heat absorbed by ice cubes

so we will have

Heat given by water to reach 0 degree C

heat absorbed by ice cubes to reach 0 degree

so we will have

so here we can say that few amount of water will freeze here to balance the heat

so final temperature will be 0 degree C

Total amount of ice will be

total amount of water

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.
