Two solid blocks are HEATED to the temperatures show. The blocks are placed so they touch. Which diagram shows the DIRECTION HEA
Setler [38]

Answer:

Heat flows from the block at high temperature to the one with lower temperature

Explanation:

The direction of heat flow is from a body at higher temperature to one with a lower temperature.

  • Temperature gradient determines the way and manner in which heat is dissipated.
  • As a system tend to increase entropy, it ensures that heat moves from hotter body to a colder body.
  • Heat movement here is by conduction as the body touches.
  • When both bodies reaches the same temperature, thermal equilibrium is established.

Determine the overall energy change for the reaction between hydrogen and oxygen shown in Question 13. Use Figure 2.
zimovet [89]

Answer:

–500KJ

Explanation:

Data obtained from the question include the following:

Heat of reactant (Hr) = 800KJ

Heat of product (Hp) = 300KJ

Enthalphy change (ΔH) =..?

The enthalphy change is simply defined as the difference between the heat of product and the heat of reactant i.e

Enthalphy change = Heat of product – Heat of reactant

ΔH = Hp – Hr

With the above formula, we can easily calculate the enthalphy change as follow

ΔH = Hp – Hr

ΔH = 300 – 800

ΔH = –500KJ.

Therefore, the overall energy change for the reaction between hydrogen and oxygen shown in the diagram above is –500KJ
