Question

ice floats on water because: ice is denser than liquid water ice molecules are smaller than water molecules ice is less dense than liquid water water has no density when frozen question 3 1 pts exothermic reactions absorb heat from their surroundings. true false

Explanation:

For the first question, density determines buoyancy. Substances less dense than the liquid they are in will float. Ice has a lower density than liquid water, allowing it to float. For the second question, exothermic reactions release heat to the surroundings, while endothermic reactions absorb heat from the surroundings.

Answer:

Ice floats on water because: Ice is less dense than liquid water
Exothermic reactions absorb heat from their surroundings. False
