A mutant lab rat was lifting weights in the gym. During its workout, it lost 50 kJ as heat and maintained a constant body temperature of 37 C. What was its change in internal energy (in kJ)?
a)-200
b)-50
c) 0
d) +50
e)+100
Temperature is constant
So, there will not be any change in internal energy. Internal energy is state function that depends on temperature.
If temperature do not change, change in internal energy will be 0
Answer: c

1) Calculate the heat through a glass window that is 30.0 cm*150 cm in area and 1.20 mm thick. Assume the temperature onthe inside of the window is 25.0�C while the outside temperature is 8.00�C. 2)Five hundred joules of heat is absorbed by a system that does 200 J of work on its surroundings. What is the change in the internal energy of the system? 3)An ideal gas expands isothermally, performing 8.80 kJ of work in the process. Calculate the heat absorbed during the expansion. 4)A gas contained in a cylinder that has a piston is kept at a constant pressure of 2.80*10^5Pa. The gas expands from0.500 m^3to 1.50 m^3 when 300 kJ...

A poikilotherm is an organism whose internal temperature varies based upon its environment - it regulates body temperature by basking or burrowing, for example a wood frog. In contrast, mammals are homeotherms, organisms which maintain thermal homeostasis. Both humans and frogs share similar enzymes. Say a metabolic reaction takes the form A → B. Its standard transformed free energy change (ΔG°) is 4.1 kJ mol-1 . (R = 8.3145 J K-1 mol-1 ). Calculate the equilibrium constant for the reaction...
