Which statement is the best example of heat energy transfer by conduction?

A cylindrical flask is being used as an insulator to store tea and keep it hot on a cold day. How will increasing the thickness by 4 times of all walls and halving the contact surface area (without changing the type of material the walls are made of) of the insulator affect the rate of heat loss?

The collision of particles within a substance results in a transfer of energy by:

Question text1. The one-dimensional heat flow equation is: [math: ρCP∂T∂t=κ∂2T∂z2+A] where ρ, Cp, and κ are the density, specific heat and thermal conductivity, and A represents heat sinks and sources. The boundary conditions in a given system are: (i) T=320 K at z=0 (ii) T=1200 K at z=40 km and we also have [math: κ=3Wm−1K−1]. Assuming no internal heat sources, calculate a) The thermal gradient of the equilibrium geotherm in [math: K/km] to two significant figures.Thermal gradient = Answer 1 Question 3[input] [math: K/km] [6] b) The temperature at a depth of 100km as predicted by this geotherm model. Give answer in K to two significant figures. T(z=100 km) = Answer 2 Question 3[input] K [4]
