Ice cubes of total mass 6.00 grams have temperature -4.0°C. Then they are placed in 50.0 grams of water at 20.0°C in an insulated foam cup. What is the equilibrium temperature of the water inside the cup? Assume that
the system is isolated. For water
Lf - 334 kJ/kg
and
2y = 2257 W/kg. The specific heat capacity of ice is 2.05 kJ/kg
°C and for liquid water is 4.19 kJ/kg . °C.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
