Chips by the Ton Tortilla chips are manufactured by submerging baked and partially cooled masa at 41 °C into corn oil at 182 °C. (a) If the specific heat of masa is 1850J/(kg.K), how much thermal energy is required to warm 0.454 kg of masa to the temperature of the oil? (b) If the production line makes 227 kg of chips every hour, at what rate (in kW) must thermal energy be supplied to the corn oil, assuming that all of the energy goes into warming the masa?

A PHYS 1510 student was working on a robotics project. The joints on the machine they were building were powered
by pistons.
Based on how hot the machine was getting, the student was able to figure out that 2.34 J of thermal energy was
produced by every piston every time the piston was fully extended to 0.4064 m.
What was the force of friction that the piston experienced during every extension?
Assume friction is the only source of thermal energy. Include units in Sl.
1.An electric kettle transfers 900 000 J of energy to some water in 10 minutes.
(a) Estimate the power of the electric kettle.
(b) How long does it take to supply 1 500 000 J of energy to heat some water?
2.Energy is measured in (a)__________________, written as J.
2. The energy transferred per unit time is called (b)__________________. Its SI unit is
(c)__________________, written as W.
3. (d)_______________________ (kW h) is also a unit of energy which is more common in
practical use. 1 kW h is equal to (e)_______________ J.
4 The electrical energy supplied to an electrical appliance can be measured using a
(f)_______________________ (readings in J) or a (g)_______________________ (readings
in kW h).
