Can you help me find the rotational kinetic energynof the rotating wheel?
A typical ten-pound car wheel has a moment of inertia of about 0.35kg⋅m2. The wheel rotates about the axle at a constant angular speed making 35.0 full revolutions in a time interval of 7.00 s
At 1 atm, how much energy is required to heat 73.0 g of H2O(s) at -20.0 °C to H2O(g) at 133.0 °C?
Vapors are likely to be non-ideal near condensation temperatures. Would you expect such behavior to make your molecular mass to high or too low?
