Explanation:
Convection requires a fluid material that can move around. Typically, metals are solid, not fluid, and therefore do not participate in convection. ... This means that metal can be either a good heat shield, a mediocre heat shield, or a bad heat shield, depending on how we use it.
When the sugar cubes are <span>placed in water, then, the mixture will be affected by stirring the water.
By stirring the water, the sugar cubes dissolve in water. The molecules of sugar cubes interact with water molecules in the jar. But when more sugar is added to the water, there comes a saturation point when no more sugar will be dissolved and it will settle down. Then, by raising the temperature the settled sugar will be dissolved too.</span>
Answer:
b
Explanation: I asked my chemistry teacher lol
The given statement is true, because the activation energy must be provided in order for the molecule to reach the transition state because it is a high-energy state. Reactant molecules don't stay in the transition state for very long since it is unstable; instead, they move on to the next phase of the chemical reaction right away.
To create a successful transition state (with lower activation energy). Heat, which is the most frequently employed energy source, favours the breakdown of processes and lowers the amount of energy needed when the enzyme attaches to the substrate.
The remainder of the process can be completed once the molecule has taken in enough energy to reach the transition state.
