An electric heater is initially at room temperature , which is 25 oC. It is turned on for 8 minutes, and consumes electric power at a rate of 44 W. The heater has a mass of 36 grams and a specific heat of 750 J/kgK. Determine the maximum possible temperature in unit of oC that the heater could reach while it is on. (Note: the maximum possible temperature would be reached if no energy is lost to the surroundings.)
Round the result to one decimal places.

A physics student uses a 115.00 V immersion heater to heat 330.00 grams of water for herbal tea. During the two minutes it takes the water to heat, the physics student becomes bored and decides to figure out the resistance of the heater. The student starts with the assumption that the water is initially at the temperature of the room Ti = 25.00°C and reaches Tf = 100.00°C.The specific heat of the water is c = 4180 J/(kg · °C)....
