0.4-l glass of water at 20°c is to be cooled with ice to 5°c. the density of water is 1 kg/l, and the specific heat of water at room temperature is c = 4.18 kj/kg·°c. the specific heat of ice at about 0°c is c = 2.11 kj/kg·°c. the melting temperature and the heat of fusion of ice at 1 atm are 0°c and 333.7 kj/kg. determine how much ice needs to be added to the water, in grams, if the ice is at 0°c. also determine how much water would be needed if the cooling is to be done with cold water at 0°c. the melting temperature and the heat of fusion of ice at atmospheric pressure are 0°c and 333.7 kj/kg, respectively, and the density of water is 1 kg/l.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
