ER 30 N Loud Area 0.2 Ara 16ml From the picture we determine that area of small piston 0.2m' and large piston 1.0m². If we are going to keep a sphere above large piston whose radius 5cm and density 12000 kg/m, then find out a) The mass of the sphere [2] b) If 30 N effort will apply small piston, the large piston will go/move up with sphere or not. PROVE MATHEMATICALLY which one you support. [4]

3) An electric heating coils supplies 1000 W of power to a metal block of mass 11 kg and raises the temperature of the block from 32°C to 65°C in 150 second. Calculate the specific heat capacity of the metal. [4] 4) -40°C (minus forty degree Celsius) means how much temperature in Fahrenheit scale? Show all term mathematically. [2] 5) 80°F means how much temperature in Kelvin scale? Show all term mathematically. [2] 6) -15°C(minus 15 degree Celsius) temperature of 2 kilograms of ice directly make vapor of 100°C. How much heat required in this case? Prove mathematically step by step. Each step 1 mark. [5] [Latent heat of fusion=33600J/kg..... Latent heat of vaporization=226800 J/kg... Specific heat capacity of ice=2100 J/kg K..... Specific heat capacity of water = 4200 J/kg k......]
