The temperature stays the same when a solid changes to a liquid because energy is required to break the forces between particles of water therefore changing the state of matter and separating the particles away from each other.
When a liquid boils, the energy is needed by the particles to escape the surface of the liquid and boil. Instead of raising the temperature, the energy goes into the particles' kinetic energy store so it has enough speed to escape the surface of the liquid.
A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Answer: Group 14
Explanation:
It's a carbon atom with 4 valance electrons.
Answer:
You can calculate the rate of reaction by dividing the change in concentration by elapsed time.You can also find it graphically by finding the slope of the concentration curve.
Explanation:
rate=quantity/t(time)
