Previous Problem List Next (1 point) A bucket of water of mass 20 kg is pulled at constant velocity up to a platform 45 meters above the ground. This takes 8 minutes, during which time 6 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform. (Use g = 9.8m/s².) Work = M (include units)

7) An insulated beaker with negligible mass contains liquid water with a mass of 0.345 kg and a temperature of 63.0 ∘C . Part A:How much ice at a temperature of -12.5 ∘C must be dropped into the water so that the final temperature of the system will be 37.0 ∘C ? Take the specific heat of liquid water to be 4190 J/kg⋅K , the specific heat of ice to be 2100 J/kg⋅K , and the heat of fusion for...

#7. A vessel whose walls are thermally insulated contains 2.70 kg of water and 0.460 kg of ice, all at a temperature of 0.0 °C. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water. How many grams of steam must condense inside the vessel (also at atmospheric pressure) to raise the temperature of the system to 27.0 °C? Neglect the heat transferred to the container.

The Joule () is the SI unit of energy. (J = kg:m? S2 A calorie is another unit of energy. The definition of a calorie is the amount of heat (energy) necessary to raise the temperature of Ig of water by 1° Celsius. Ig of water occupies 1 milliliter (ml) = 1 cubic centimeter (cm) of volume. lkcal=4186J Energy comes in many forms and energy may be converted...
