What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.
Why do you use hot water to open the metal lid of a jar?
Using hot water to open a metal jar lid helps to expand the metal, making it easier to twist open the jar. The heat from the hot water causes the metal to expand while the glass of the jar remains relatively unaffected, creating a temperature difference that helps to loosen the lid.
Metal lids on glass jars can often be loosened by running hot water over them. Why does that work?
Running hot water over a metal lid on a glass jar causes the metal to expand slightly due to the heat, which can help break the seal it has with the glass jar. This expansion makes it easier to twist the lid open.
When a cube of hot metal is place in a beaker of cold water the temperature of the water?
The temperature of the water will increase as heat is transferred from the hot metal cube to the cold water until thermal equilibrium is reached.
Why is it required to tap the hot metal with a tissue paper before placing the hot metal in the calorimeter?
Tapping the hot metal with a tissue paper removes excess water or moisture on the surface, ensuring that only the thermal energy from the metal is transferred to the water in the calorimeter. This helps to prevent any additional heat transfer that may affect the accuracy of the calorimetry experiment.
When a metal and a black plastic is put into hot boiling water at the same time which gets hot first?
the metal.
How do you remove a ceramic bowl wedged in a stainless steel pan?
Put some ice in the ceramic bowl and let it sit for a while then put the bottom of the metal in hot water. Don't let the hot water get to the ceramic. The ice will shrink the ceramic and the hot water will expand the metal. They should come apart.
What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Can you put hot or cold water on shingles?
yes you can put hot and cold water on shingels
What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?

What is a better insulator for a hot water pipe metal or nonmetal?
Non-metal
Why when you dunk a hot red metal into water does the water not boil?
When a hot red metal is immersed in water, a layer of vapor forms around the metal, insulating it from direct contact with the water. This layer of vapor prevents the water from coming into contact with the metal and reaching boiling temperature. As a result, the water does not boil immediately.
What is a metal used in hot water pipes?
Copper
What is the worst insulator for hot water?
tin or metal
Do goldfishes like hot water?
No, if you put a goldfish in hot water it will die.
Why does water not get hot as metal on a sunny day?
it is because metal is a good conductor of heat
Why does water evaporate when the hot metal touches the water?
it is conducting the heat away
