Is there heat transfer when baking a potato at 20 â°c in an oven at 200 â°c.

a. true
b. false

a) True

Explanation:

When two bodies at different temperatures (in this case the potato and the oven), get in touch each other, thre exists a heat transfer from the body at the higher temperature to the one with lower temperature, until both reach to a same temperature, state which is known as thermal equilibrium.

We assume for simplicity, that the oven is perfectly adiabatic, so it can't exchange heat with anything outside.

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
