A curious student decides to conduct an experiment for understanding the relationship between thermal energy, phase change and temperature. With this purpose in mind, he picks ice cubes of total mass 130 grams initially at - 20°C. He then starts heating up the system until all ice cubes disappear and transform into steam. The final temperature of the steam is recorded as 120.5°C. Assuming no heat is lost to the surroundings, calculate the total amount of heat energy gained by the ice cubes during this process. (Note that Cwater= 4186 J/ kg°C, Cice = 2090 J/ kg°C, cte am = 2010 J/ kg° C, L,= 333 kJ/ kg, L,=2.6x10° J/ kg.) Q= J

On his honeymoon, James Joule traveled from England to Switzerland. He attempted to verify his idea of the inter-convertibility of mechanical energy and internal energy by measuring the increase in temperature of water that fell in a waterfall. For the waterfall near Chamonix in the French Alps, which has a 120-m drop, what maximum temperature rise could Joule expect? He did not succeed in measuring it, partly because evaporation cooled the falling water and also because his thermometer was not sufficiently sensitive.
For a temperature increase of 10 at constant volume, what is the heat absorbed by (a) 3.0 mol of a dilute monatomic gas; (b) 0.50 mol of a dilute diatomic gas; and (c) 15 mol of a dilute polyatomic gas?
One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?
To help prevent frost damage, 4.00 kg of water at 0 is sprayed onto a fruit tree. (a) How much heat transfer occurs as the water freezes? (b) How much would the temperature of the 200-kg tree decrease if this amount of heat transferred from the tree? Take the specific heat to be 3.35k J/kg. , and assume that no phase change occurs in the tree.
In a study of healthy young men[1], doing 20 push-ups in 1 minute burned an amount of energy per kg that for a 70.0-kg man corresponds to 8.06 calories (kcal). How much would a 70.0-kg man's temperature rise if he did not lose any heat during that time?
Why is a person able to remove a piece of dry aluminum foil from a hot oven with bare fingers, whereas a burn results if there is moisture on the foil?
For the human body, what is the rate of heat transfer by conduction through the body's tissue with the following conditions: the tissue thickness is 3.00 cm, the difference in temperature is 2.00 , and the skin area is 1.50 m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)
A 2.0-kg aluminum block is originally at 10 degrees celcius. If 36 kJ of energy are added to the block, what is its final temperature (in Kelvin)? The specific heat of aluminum is 900 J/kg K The answer (in fundamental SI unit) is ___________ (type the numeric value only)
Initially you have mwater=4.2kg of water at Twater=66 degrees celcius in a insulated container.
