endothermic
what does endothermic mean
it takes in energy
what does exothermic mean
it releases energy
what does photosynthesis take energy from
the sun
why do endothermic reactions feel cold to the touch
it pulls the heat out of your hand
can an exothermic reaction be reversed? if so, what would be reqiured
no, because exothermic reactions are chemical reactions and you can't reverse chemical reactions
why do plants do photosynthesis
to survive
when cooking the egg, heat is absorbed from the stove. how does this represent an endothermic reaction
the stove is making heat but the heat travels to the egg so the egg takes in heat which means it is a endothermic reaction
what reaction takes place when your running
exothermic
what is the process of photosynthesis
plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
in an endothermic reaction, why might the system need a consistent input of energy
because if it isn't constantly taking in energy then it isn't considered an endothermic reaction
why do some exothermic reactions require an initial energy input
do plants need photosynthesis
no, some plants can survive in the dark if they have water, minerals, and carbon dioxide. they might look weird though
can an endothermic reaction turn into a exothermic reaction depending on its conditions
yes, if the surroundings become colder than it releases heat instead of taking in heat
how do exothermic reactions contribute to global warming
because they heat up the atmosphere, that makes the icebergs melt and sea levels rise
what are 3 main things that can effect photosynthesis
amount of sunlight, the temperature, and carbon dioxide concentration
