please help! An ice cube (25 g) is removed from a freezer at 0 °C. How much energy is required to completely melt the ice cube?

So it takes 80 calories of heat to melt 1 g of an ice cube, now do the math. (Hope this helped)

Explanation:

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
