When you measure the temperature of hot soup you are measuring the?
... amount of energy in the soup molecules.
What changes in the hot pack over the course of the demonstration?
Amount of thermal energy
Does a copper rod increase in mass when heated?
Only an insignificant amount, due to mass-energy equivalence - the added energy implies some added mass.
What two forms of energy could best be used to increase the temperature of a sheet of copper?
heat and light
The greatest amount of heat energy transferred between the hot and cold water is transferred by the process of?
absorption
How can astronemers infer how hot a star is?
By the amount of energy that they are giving out.

How much energy is saved when Copper is recycled instead of mined?
Recycling copper saves fifteen percent of the energy used in producing the same amount from copper ore. Recycled copper has exactly the same qualities as copper from ore, so it can be recycled over and over without any loss. Copper is non renewable, so it is important to conserve it. Energy saved means fewer greenhouse gas emissions from the fossil fuel saved.
Why is copper used for hot water pipes?
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes

hot water

What happens when red hot copper is dropped in water?
Dropping a chunk of red hot copper in water will create a big hiss and the emission of steam from the container. The thermal energy of the copper will be transferred to the metal. The copper metal will cool rapidly and become brittle. If a copper wire is heated to a high temperature and quenched (cooled rapidly by immersion), it will harden and become less flexible than it was.
The greatest amount of heat energy transferred between the hot and cold water is transferred by the process of?
absorption
How much copper is in a copper necklace?
There is no one exact amount of copper found in a copper necklace, each jeweler would make their necklaces with a small amount of copper. Copper has been used throughout history as a healing metal, and the body needs a certain amount of copper to function. If one isn't getting enough copper in their diet or through supplements, they can wear copper jewellery.
