Why in an Endothermic reaction does the experiment become colder?

So i know that endothermic reactions taken in energy from the surroundings and this leaves the surroundings and experiment colder, but why? Surely if the experiment is taking in heat it should be hotter right?

Thanks in advance
The actual reaction requires more energy breaking bonds than making them releases.
Breaking bonds requires energy, which is why the reaction takes in energy from the surroundings. This causes the heat from the outside environment to drop because energy is being taken into the reaction.

In an exothermic reaction, more energy is being released from making bonds than is being taken in from breaking them, which is what heats up the outside environment. It's all about whether the net energy ends up being more taken in or more released.
I'm not sure if that explains things any better, sorry :smile:

Heat is taken in from the sorroundings - so the sorroundings get cooler.
