A jet of steam at 100degrees Celsius is directed on a large block of ice at 100 degrees Celsius for a short time. o.4 kg of steam condenses to form water and some ice is melted at 8 degrees Celsius. Calculate the heat given out by this mass of steam in converting to water without a change in temperature. calculate the heat given out by this steam in changing to water without change in temperature specific latent heat of vaporisation of water as 2200kj/kg ii calculate the heat given out by this water as it cools to the temperature of the ice heat capacity to be 4.2kj/kg

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
