You may feel cold when you touch certain kinds of matter because some matter gives off cold air. I’m NOT SURE
This is thermal conduction.
In conduction area with higher kinetic energy (in this case how water) transfer thermal energy to an area with lower kinetic energy (in this case frozen vegetables). Thermal c<span>onduction takes place in all phases of </span>matter (solids, liquids, gases). Rate of conduction is proportional with <span>temperature difference between substances.</span>
Because when you take the sand out it doesn't stay the same shape
