I think this is learned in chemistry do you have any notes that can help
It should be noted that when a reaction is occurring in a test tube, heat transmitted to the surroundings when Molecules collide with the glass, and the glass molecules then transmit that energy to the outside.
<h3>What is heat?</h3>
Heat can be regarded as a form of energy which is energy that is been transferred as a result of difference in temperature.
In the case above, Molecules collide with the glass, and the glass molecules then transmit that energy to the outside which is an exothermic reaction.
Therefore, option B is correct.

Mark me brainiest pls it right answer
The human gametes differ from all the other cells in the body because the somatic cells have a complete set of chromosomes
Answer:
Keep temperature constant and increase the pressure of the reaction. The rate of reaction increases.
Explanation:
First of all, the question is asking us to design an experiment to investigate the effect of pressure on the rate of reaction hence the pressure can not be held constant since it is the variable under investigation. This eliminates the first option.
Secondly, increasing the pressure of the reaction means that particles of the gas collide more frequently leading to a greater number of effective collisions and a consequent increase in the rate of reaction according to the collision theory.
Hence the answer above.
