The temperature coefficient of resistance α in equation R(T)=R0[1+α(T−T0)] equals the temperature coefficient of resistivity α in equation ρ(T)=ρ0[1+α(T−T0)] only if the coefficient of thermal expansion is small. A cylindrical column of mercury is in a vertical glass tube. At 20 ∘C, the length of the mercury column is 12.0 cm. The diameter of the mercury column is 1.6 mm and doesn't change with temperature because glass has a small coefficient of thermal expansion. The coefficient of volume expansion of...

I need help with these two 1 The table below shows time, temperature, and temperature change data collected using Pivot Lab#8 (Specific Heat of Water Experiments). The heat supplied, Q, is to be calculated from Q = Pt (where P is the power of the light bulb which is 25 watts and t is the time). For example, when t = 200 s, Q = 25 watts x 200 s = 5000 Joules. Plot Temp. Change (vertical axis) versus Heat...
