Jenavius placed a marshmallow in the microwave to make a smore for desert. the marshmallow expanded when it was heated. how can you best describe why this happened? a) as the marshmallow was heated the particles moved faster increasing its volume. b) as the marshmallow was heated the particles moved faster decreasing its volume. c) as the marshmallow was heated the particles moved slower increasing its volume. d) as the marshmallow was heated the particles moved slower decreasing its volume.

A) As the marshmallow was heated the particles moved faster increasing its volume.

Explanation: When heat is supplied to the marshmallows, the kinetic energy of the marshmallows increase and thus they start moving randomly and thus the molecules occupy more volume and volume increases.

As we know kinetic energy is directly related to temperature, thus as temperature is increased, the kinetic energy of the molecules also increase.

R = gas constant

T= temperature

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
