Why is a reaction exothermic? Exothermic Reactions In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants. In the presence of water, a strong acid will dissociate quickly and release heat, so it is an exothermic reaction. How do you determine if […]

What is the main difference between passive and active transport?
What is the main difference between passive and active transport? There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. What are the […]
Does high pressure mean low temperature?
Does high pressure mean low temperature? The positions of high and low pressure centers can greatly influence a forecast. Fair weather generally accompanies a high pressure center and winds flow clockwise around a high. This means that winds on the back (western) side of the high are generally from a southerly direction and typically mean […]
