(a) how much heat transfer (in kj) is necessary to raise the temperature of a 0.190 kg piece of ice from −18.0°c to 134°c, including the energy needed for phase changes? (assume the substance remains at a constant volume throughout each stage of the heating process.) (b) how much time (in s) is required for each stage, assuming a constant 19.0 kj/s rate of heat transfer? (enter your answers as a comma-separated list. enter your times in order from the earliest stage to the final stage of the heating process.)

Your town is considering building a biodiesel power plant describe at least two advantages and two disadvantages

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
