A recipe for candy requires that the liquid ingredients be stirred constantly until the liquid reaches a temperature of 140°C. What type of spoon – wood or metal – will prevent burns to a person’s hand while stirring the hot liquid? Explain your choice.

Wood because

Explanation:

The wooden spoon would be the best to use because, it is an insulator which means it won't get as hot as the metal spoon. The metal spoon is a conductor meaning it will absorb the heat. Which could burn someone.

Hope this helps!^^

Stank you -w-

Explanation:

A wooden spoon will prevent the person’s hand from burning because wood is an insulator. An insulator slows the transfer of thermal energy so that very little thermal energy from the hot liquid will transfer to the person’s hand.

Sample Response

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
