Questions on Specific heat capacity and Specific
... aluminium and 1 mol of copper by the same amount are about the saem. Yet the specific heat capacities of the two metals are very different. Suggest a reason for this. 4) A car of mass 1360 J descends from a hill of height 86 m at a constant speed of 20 km h-1. Assuming that all the potential energy ...

Mechanisms of Heat Transfer
... • If left alone for sufficient time, both objects will come to thermal equilibrium • The smaller the value of k, the slower the heat transfer • Home insulation strives to maximize this transfer time (high R-value), allowing for a temperature gradient to exist longer ...

Subtracting Integer
... The lowest point in the Pacific Ocean is about -11,000 meters. The lowest point in the Atlantic Ocean is about -8,600 meters. Which ocean has the lower point? How much lower? • Which Ocean has a lower point and why? Pacific Ocean because -11,000 means that it is 11,000 meters under sea level. • How ...

Heat - Cobb Learning
... How does heat affect the state of an object? • The state of a substance depends on the speed of its particles. The speed and freedom is known as Entropy. • Adding energy in the form of heat to a substance can result in a change of state. • Removing energy in the form of heat from a substance can re ...

... dW = work done by the system dU = change in internal energy of the system The choices are a combination of adding or removing heat from a system and the compression or expansion of a system. With the above definition, when we add heat to the system, dQ is positive. Conversely dQ is negative when hea ...

Teacher`s notes 21 Specific Heat Capacity for a liquid
... If you do not have access to a commercial calorimeter you can make one from a metal can or even glass beaker. Results will not be quite as accurate but this can be used to get students to explain sources of error. A heater can be crafted out of nichrome wire. A doubled strand about 20 cm coiled make ...
