What is the effect of temperature on viscosity? The former effect causes a decrease in the shear stress while the latter causes it to increase. The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the […]

Why is calorimeter made of copper? Answer: Cu has low specific heat capacity and thus it reaches the equilibrium temperature quickly by absorbing a small amount of heat. Cu is highly malleable and hence a very thin box of small mass can be made thus decreasing the heat capacity of the box. Why is the […]
