Is thawing meat a physical or chemical change?
Thawing meat is a chemical change because the meat isn't changing the meat is just melting but it's not changing shape or flavor or texture etcIt's a physical change the water is changing from solid - ice, to a liquid. The meat is not changing.
How can an ice sculpture contain more heat energy than a lit match?
It's all a matter of mass. An ice sculpture contains 1 british thermal unit for each pound of ice and every 2.14 degrees Fahrenheit above absolute zero. a burning match gives off approximately 19000 btu per pound in heat energy as it burns. Thus the match, assuming it weighs 14 grains, will give off approximately 38 btus of heat energy until it is fully consumed; whereas a 100lb ice sculpture at 30 degrees fahrenheit contains in total heat energy approximately 20,000 btus more or less. Temperature wise the match is hotter than the ice, but it would melt only a fraction of 1 lb of ice if all the energy were absorbed by the ice. (1 lb of ice requires 144 btus to melt at 32F).
Why is energy absorbed when ice melts?
When an ice cube gains energy, it is the same as gaining heat. So if an ice cube is getting warmer, it melts.
