How to calculate the final temperature of the room
A 3 m x 3 m x 2.4 m room losses heat through the walls at a rate of 520 W. Determine the final temperature of the room after 2 hrs with the electric baseboard heater drawing 120 V and 4.5 A. The initial temperature of the room is 15 °C

State the null hypothesis for a chi-squared test of independence between the two variables. Specify the variables.
Consider nitrogen gas contained in a piston-cylinder arrangement. The cylinder diameter is 150 mm. At the initial state the temperature of the N2 is 500 K, the pressure is 100 kPa, and the height of the gas column within the cylinder is 200 mm.
A machine consists of two components, whose lifetimes have the joint density function f(x,y) = 1/50, for x>0, y>0, x+y<10. The machine operates until both components fail. Calculate the expected operational time of the machine.
If the particle's velocity is perpendicular to the magnetic field at all times, what is the magnitude if the magnetic force exerted on the particle?
Half a mole of a monoatomic ideal gas is initially at 1000 K and a pressure of 20 bar. It is expanded adiabatically and reversibly until the final temperature is 400 K. Calculate the final volume and pressure.
The data below are the temperatures on randomly chosen days during a summer class and the number of absences on those days. Construct a 95% confidence interval about the slope of the true least-squares regression line, for the data below, given th
A piston-cylinder device, with a free floating piston, contains 2 kg of water as a saturated liquid with a pressure of 400 kPa. The water is then heated to a saturated vapor. What is the amount of boundary work?
An engine oil supposed to have a mean viscosity of µ = 85.0. A sample of n=25 viscosity measurements resulted in a sample mean of 88.3 and sample std.=7.49. Is there overwhelming evidence that mean viscosity is not as stated?
