the phase change of boiling has more kinetic energy.
boiling is a liquid ---> gas
melting is solid ---> liquid
in a liquid, there is medium kinetic energy but when a liquid is boiled it turns into a gas and gains more kinetic energy, so there is more movement and the particles move freely as there is high KE.
in a solid, there is low kinetic energy as the particles vibrate in fixed positions. a solid gains kinetic energy when it becomes a liquid (melting) and there is medium kinetic energy.
there is a higher amount of kinetic energy when a substance is boiled.
therefore, the answer is boiling.
nononono JUST NO NOOOOOOOOO
Answer:
Independent variable: different alcohols
Dependent variable: red dye
I think the best answer is migration. In an alpine biome, animals have two problems which is the very cold temperature and the UV rays from the sun. Most alpine animals hibernate and migrate to warmer areas of the mountains when the temperature continues to drop.
Answer: The final pressure is 75 mm Hg.
Explanation:
According to Boyle's law, at constant temperature the pressure of a gas in inversely proportional to volume.
Since, it is given that the temperature is constant. Hence, formula used is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the final pressure is 75 mm Hg.
