CAN SOMEONE PLEASE HELP ME AND TELL ME IF IM RIGHT
Explain which statement is correct: energy is lost when water is boiled or the energy used to boil water is present, but it is no longer in a usable form unless you use work or heat to make it usable.
i think that the 2nd one is correct because i no that energy is not lost when water is bpiled it is gained because of the bubbles and electrons and atoms moving around. am i right??
You're on the right track, but there is a slight clarification needed. The second statement is indeed correct, but let's break it down to fully understand why.
When water is boiled, energy is indeed used to convert the liquid water into steam. This energy is typically provided in the form of heat, like when you heat water on a stove. So, the energy used to boil water is present during the boiling process.
However, the key point is that the energy used to boil water is no longer in a usable form unless you do something with it. In this case, the energy is now in the form of steam, which is a high-energy gas. It still contains the same amount of energy that was used to boil the water, but it cannot be readily utilized in its current form.
To make the energy usable, you can convert it back into a different form, such as heat or work. For example, you can capture the steam to perform work in a steam engine or use it to heat another substance. In these cases, the energy is being converted into a usable form, either as mechanical work or heat.
So, yes, the energy used to boil water is not lost but rather present in the steam. However, it needs to be converted into a usable form (heat or work) to be effectively utilized.
