A 1400 kg car moving at 115 km/h could be converted entirely into heat. What amount of water could be heated from 25 ∘C∘C to 49 ∘C∘C by the car's energy? Recall that 4.184 JJ are required to heat 1 gg of water by 1∘C∘C.

How much energy is required to convert 4.9kg of ice at 0C to water at 31C ?  How much energy is required to convert 4.9kg of ice at 0C to water at 31C ?  The latent heat of fusion of ice is: Lf=3.33×105J/kgLf=3.33×105J/kg The specific heat capacity of water is 4186J/kg∘C

One way to keep the contents of a garage from becoming too cold on a night when a severe subfreezing temperature is forecast is to put a tub of water in the garage. If the mass of the water is 122 kg and its initial temperature is 24.2°C, how much energy must the water transfer to its surroundings in order to freeze completely? The specific heat of water is 4186 J/kg·K, and the latent heat of fusion is 333 kJ/kg.

how much he is required from The environment to warm up 800 KG humans from 37C to 37.5C in joules?

How much energy does it take to raise the temperature of 6.5 pounds of water from 68 deg. F to 212 deg. F?

How much heat is needed to completely vaporize 20 grams of ice, initially at 5°F?

What total amount of heat must be removed to drop the wholebody temperature of a typical 65-kg patient in this study by 1.0 °C? Because the human body is mostly water, the average specific heatof the human body is relatively high, 3.5 * 103 J>1kg # K2.A. 3.5 * 103J B. 2.3 * 105JC. 5.4 * 106J D. 6.2 * 107J

2.10 kg of mercury (Hg) at 205 °C is mixed with 0.110 kg of water at 80.0 °C A in a well-insulated bucket of negligible heat capacity. What mass of water in grams that will transform to vapor? CHg = 139 J/Kg °C Cwater = 4186 J/Kg °C Lv, water = 22.6 x 105 J/Kg

The heat required to melt a block of ice is 1165500 J. Estimate the total heat required to vaporize the same mass of water that is at 50 °C. ( Cwater = 4186 J/kg.°C, Lf = 3.33 × 105 J/kg, and Lv = 2.26 × 106 J/kg.)

In the laboratory, calorimetry can be used to determine the latent heat of fusion of water, LfLf. If an ice cube of mass 30.0g30.0g at 0∘C0∘C is added to a calorimeter cup of mass mc=60.0gmc=60.0g that contains water of mass 170g170g at an initial temperature TiwTiw of 20∘C20∘C, after the ice melts, the final temperature of the water TfwTfw is found to be 5.57∘C5.57∘C. Based on this data, what is the latent heat of fusion of water? The specific heat capacities of water and the calorimeter are  4186J/(kg.K)4186J/(kg.K) and 900J/(kg.K)900J/(kg.K),  respectively
