Answer:
Temperature
Explanation:
temperatures below 0 degrees celsius will turn water into ice
Temperatures 1 to 99 degrees celsius is water in liquid form
Temperatures of over 100 degrees celsius liquid turns into gas
Answer:
False
Explanation:
A liquid has a definite shape and takes on the volume of its container. A gas has both the shape and the volume of its container. The particles in a gas cannot be compressed into a smaller volume. Liquids tend to contract when heated.

It’s transformed to heat, therefore the type of energy that has the electrical energy been transformed into heat
Answer:
Acids:
Bases:
Explanation:
According to the Bronsted-Lowry acid-base theory, an acid is a proton donor and a base is a proton acceptor. In this case, notice that donates a proton, since after it loses a proton, it becomes a chloride anion. Therefore, is a Bronsted acid.
Similarly, is a proton acceptor and, therefore, a Bronsted base, since it becomes .
If we look at the reverse reaction, chloride can gain a proton to become , meaning it's a conjugate base.
Finally, is a conjugate acid, since it can donate a proton to chloride.
Answer:
Explanation:
1 : apple sliced : the apple was cut into smaller peices : physical change
2 : smashed apple : the apple became a mush : physical change
3 : paper burned : the paper became ash : chemical change
4 : glow stick snapped : the glow stick started glowing : chemical change
5 : apple being burned : the apple became discoloured and turned coal-like : chemical change
_____
2. it does not alter the chemical make up of the apple
3. because it changes to a new substance entirely, changing the chemical make up of the paper to make it something new
4. smashing the apple, because you mash up the apple with your teeth in your mouth
5. The apple being burned is being chemically broken down to form a new substance, the same way your stomach digests food to break down and use for other reasons.
