A circular hole is cut through a flat aluminum plate a spherical brass has a diameter of the holethe plate and the ball have the same temperature at all times should the plate and ball be heated?

If both the aluminum plate and the brass ball are at the same temperature, heating them will increase their temperatures uniformly. However, since the brass ball has a different thermal conductivity than aluminum, the heat distribution might differ after heating. The circular hole ensures a snug fit, which could affect heat transfer between the two materials. Overall, both materials will expand when heated, but their different properties may lead to varying effects on the fit and thermal interaction.
