Problems

Subject: Physics                                                                       Grade: 8

Chapter: Heat

Solve the following problems

1.      Calculate the amount of heat needed to heat 10 kg of water at 50 ° C. 2.      Calculate the amount of heat required to heat an aluminum spoon weighing 50 g from 20 to 80 ° C. 3.       What amount of heat was released when the oil was cooled, the volume of which is 20 liters, if the temperature changed from 60 to 20 ° C? (c=1800 J/kg C; ρ=900kg/m3) 4.       How much heat will it take to heat 2 liters of water from 20 ° C to boiling in an aluminum pot weighing 200 g? 5.       How much will the temperature of the water in the glass change if the amount of heat equal to 100 J is transferred to it? The capacity of the glass is 200 cm3. 6.       A heated stone weighing 10 kg, cooling in water at 1 ° C, transfers 4.2 kJ of energy to it. What is the specific heat capacity of a stone? 7.       What is the mass of a cast-iron block if, when it was cooled from 1115 to 15 ° C, 190.08 MJ of heat was released? (c=540 J/kg C)
