Answer:

The temperature of a boiling liquid remains constant until all of the liquid has been converted to a gas.For example, the amount of heat necessary to change one gram of water to steam at its boiling point at one atmosphere of pressure,  the heat of vaporization of water, is approximately 540 calories.

lbvjy [14]

Answer:

For iron

Final temperature = 54,22°C

For copper

Final Temperature = 63.67 °C

Explanation

Hello,

You are using a torch to warm up a block of iron that has an initial temperature of 32°C.

The first you have to know is that the "heat capacity" could simply define as the heat required to go from an initial temperature to a final temperature.

So you need to use the heat capacity equation as follow in the paper.

The equation has to have all terms in the same units, so:

q = 12000 J

s = 0.450 J / g °C

m = 1200 g

Ti = 32 °C

Lelechka [254]

gas to liquid

Explanation:

The change of state indicated by this analogy is from gas to liquid.

Cylinder to the left is filled with gases

Cylinder to the right is made up of liquid.

  • Gases occupy the volumes of containers they are introduced into.
  • They are random and possess a high kinetic energy.
  • Liquids have definite volume and flow with one another.
  • The gases in A are dispersed and in random motion.
  • This phase change is called condensation
