5x1005x100 5x1005x100 Ms. Al-Khalifa’s water reached 100 degrees Celsius but its not boiling why?
5x2005x200 5x2005x200 Ms. Al-Khalifa is trying to cook meat for her family using a pot but it takes a very long time and needs to add water many times as it evaporates very quickly. What can she use to help make her cooking time less and more easier? Why?
5x3005x300 5x3005x300 Ms. Al-Khalifa traveled to Alaska for a 3 month training course. She is starting her car but its not running. The repair man told her she forgot to put antifreeze in her car engine. Why is that important?

6x1006x100 6x1006x100 Amount of heat energy needed to raise 4 kg of water 20°C. Specific heat of water is 4200J/kg˚C
6x2006x200 6x2006x200 What is the temperature change from a liquid to a solid in this graph?
6x3006x300 6x3006x g of mercury is heated from 25°C to 155°C, and absorbs 455 joules of heat in the process. Calculate the specific heat capacity of mercury.
6x4006x400 6x4006x400 To what temperature will a 50.0 g piece of glass raise if it absorbs 5275 joules of heat and its specific heat capacity is 500 J/kg°C? The initial temperature of the glass is 20.0°C.
6x5006x500 6x5006x500 A 5.5kg brass ball at 120 o C is placed in an insulated container of water at 20 o C. When the ball and the water reach thermal equilibrium, their temperature is 50 o. The Specific Heat for brass is 380 J/kg o C and water is 4200 J/kg o C. What is the mass of the water? HINT: heat gained = heat lost
