When 1.65 x 105 J of heat transfer occurs into a meat pie initially at 20.0°c, its entropy increases by 470 J/K. What is its final temperature (in degrees)? 114.9 °C
On a hot summer day, 3.50 ✕ 106 J of heat transfer into a parked car takes place, increasing its temperature from 36.5°C to 44.4°C. What is the increase in entropy (in J/K) of the car due to this heat transfer alone? On a winter day, a certain house loses 5.80 ✕ 108 J of heat to the outside (about 550,000 Btu). What is the total change in entropy (in J/K) due to this heat transfer alone, assuming an average...
Five kg of oxygen (O2), initially at 430C, fills a closed, rigid tank. Heat transfer from the oxygen occurs at the rate 425 w for 10 minutes. Assuming the ideal gas model with k = 1.350 for the oxygen, determine its final temperature, in °C.
5. True/False: For a given transfer of energy, a greater change in entropy occurs when the temperature is high. False, because as temperature decreases there is a greater change in entropy. False, because only heat flow affects the change in entropy, not temperature. True
A heat transfer of 7.5×105 J is required to convert a block of ice at -11 ∘ C to water at 15 ∘ C What was the mass of the block of ice?
A metal part is undergoing a heat-treating process, it has a mass of 12 kg and is initially at 950∘C. The part is quenched in a tank containing 225 kg of water, initially at 35∘C. Consider the heat transfer between the tank and its surroundings to be negligible. Taking the specific heat of the metal part and water as constant at 0.5 kJ/kg.K and 4.2 kJ/kg.K respectively, determine : The final equilibrium temperature after quenching Tf= ∘C The amount of...
