Solve the all parts of given question:
Question: We are going to heat up some water. We start with 10 kg of ice at T = -20° C.
Part A: When we finish we have the same amount of water at 120°C, at standard pressure. What is the volume of the Steam produced?
Part B: How much heat did we need to add to the system to make this change?
Part C: If the heating is done with a propane burner putting out 25,000 BTUs, how long will it take to do this?
Please show all work and steps I am really trying to learn this for my exam.
A positive charge of 5.50 C is fixed in place. From a distance of 3.70 cm a particle of mass 5.60 g and charge +3.10 C is fired by an initial speed of 80.0 m/s directly toward the fixed charge. How close to the fixed charge does the particle obtain b..
