The one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

Explanation:

A substance like metal box that has high temperature will have more kinetic energy between its molecules due to which there will be more number of collisions between them.

Hence, it is able to transfer its heat energy more  readily ac compared to a substance with low heat energy.

As a result, in the given diagram as temperature is increasing from block A to block B so heat energy will be transferred from block D to block A.

Thus, we can conclude that one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
