- A container holds 102.9 liters of Oxygen at 268.4K and a pressure of 1.95 atmospheres. How much heat is required to raise the temperature of this gas to 314.1K, holding the volume constant? Give your answer in kJ. Treat the gas as an ideal gas. Note: It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.Calculate the actual work done on the 200 g mass using W = mgh. Be careful to use only the change in height of the mass. How does this compare to the work done by the gas from step C? Does the gas do any work other than lifting the 200 g mass? The given, instructions, and calculations are all indicated in the image.The figure to the right shows a pV-diagram for 0.0040 mole of ideal H2 gas. The temperature of the gas does not change during the segment bc. What volume does this gas occupy at point c?
- The pV diagram in the figure (Figure 1) shows a process abc involving 0.350 mol of an ideal gas. What was the temperature of this gas at points a, b, and c?

I keep gettign 707 watts and that is not correct. Seals may cool themselves by using thermal windows, patches on their bodies with much higher than average surface temperature. Suppose a seal has a 0.030 m2 thermal window at a temperature of 30∘C. If the seal's surroundings are a frosty -15 ∘C, what is the net rate of energy loss by radiation? Assume an emissivity equal to that of a human. Express the answer in watts. Thank you for the help! It is appreicated.Calculate the actual work done on the 200 g mass using W = mgh. Be careful to use only the change in height of the mass. How does this compare to the work done by the gas from step C? Does the gas do any work other than lifting the 200 g mass?

Explain and show your solution.If you have 4 moles of a diatomic ideal gas (such as oxygen or nitrogen), how much heat is required to raise the temperature of this gas from 269.5K to 288.3K if the volume of the gas remains constant during the heating? Note: It is understood that your answer is in units of Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("J" in this case), you answer will be counted wrong.Calculate the actual work done on the 200 g mass using W = mgh. Be careful to use only the change in height of the mass.

- In a container of negligible mass, 0.360 kgkg of ice at an initial temperature of -39.0 ∘C∘C is mixed with a mass mm of water that has an initial temperature of 80.0∘C∘C. No heat is lost to the surroundings. Part A If the final temperature of the system is 19.0 ∘C∘C, what is the mass mm of the water that was initially at 80.0∘C∘C? Express your answer with the appropriate units. mm = nothingnothing SubmitRequest Answer Return to AssignmentIf you add boiling water to a cup at room temperature, what would you expect the final equilibrium temperature of the unit to be? You will need to include 1he surroundings as pan of the system. Consider the zeroth law of thermodynamics.Suppose a gasfilled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0C. (a) Find the gauge pressure inside such a bulb when it is hot, assuming its average temperature is 60.0C (an approximation) and neglecting any change in volume due to thermal expansion or gas leaks. (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand. What will the actual final pressure be, taking this into account? Is this a negligible difference?
