The water must be heated.
Ice cream feels cooler to our teeth than ice cold water because during the change of state some amount of heat is absorbed which is known as Latent Heat. So in ice no hidden heat is absorbed while in cool water latent heat of fusion or melting is absorbed.
yes salt water is heat quicker
If a hydro-carbon is burnt it will make heat, CO2 and water however if a hydro-carbon is heated it will just expand into its surroundings
some of the energy,however, is absorbed by the land and water and change into heat
Natural Gas, CH4, is rapidly oxidized producing heat, CO2 and water. The heat is absorbed by the wire gauze and surrounding atmosphere.
Earth's atmosphere is mainly heated from the ground up because the heat is absorbed into the ground. The warmed surface of the earth then emits heat as infrared radiation which rises into the atmosphere. There the greenhouse gases like water vapour, carbon dioxide and methane absorb and hold the heat.
When it is evaporating
The hotness of water proves heat is absorbed by water so the process is exothermic which releases the heat and is absorbed by water.
No, no heat is involved when mixing baking powder and water.
yes
Melt.

Than water? Yes
