(a) In your own words differentiate between heat and temperature. (4 ) (b) On a hot day, the temperature on the Fahrenheit scale changes by 10 \"F. Calculate the corresponding change on the Kelvin scale. (4 ) (chi 50 g ice cube at -5 \"C is taken out of a freezer. Heat is then added until all of the ice is transformed to steam at 100 0It}. Determine the amount of heat that was added in kJ. (6 ) (d)You are provided with a metal block having dimensions of 124 mm x 100 mm x 45 mm. Explain how you should place the block on the surface of a oor so that minimum pressure will be exerted by the block on the oor. Calculate the minimum pressure if the mass of the block is 10 kg. (6 )
