Answer:
- Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles.
- Convection is the heat transfer due to the movement of a fluid, such as a gas or liquid, and carries heat energy away from the source of heat. When a substance is heated, it causes its particles to vibrate more. The more vibration, the more space they will take up and the less dense they will become.

Answer:
The time required to produce a given quantity of a product is inversely proportional to the rate of the reaction. For a reaction that runs twice as fast, the given quantity of product will be produced in half of the time.
Explanation:
As the reaction progresses to form products, the number of successful collision decreases with increase in time and as rate increases with an increase in the collision between reactants, then time decreases.
With an increase in the system temperature, concentration, surface area and the presence of catalyst, the reaction rate increase alongside decreasing the time needed to turn reactants to products.
For instance, the presence of a catalyst in a reaction speeds up or increases the reaction rate thereby providing an alternative route or pathway to the products thereby decreasing the time of product yield and lowering the activation energy of the reaction.
Therefore as the rate increases, the time needed to convert reactants to products decreases
