Answer:
a pencil being sharpened
freezing water
boiling water
Explanation:
a physical change doesn't change the chemical structure of an object. That is why the other 2 are wrong
The answer would for sure be 178 because acid & base make that amount so yea!! I’m talllyyy right
THe Answer is 105 J
hope this helps and please brainliest, I was first :)
Answer:
Specific heat of solid A is greater than specific heat of solid B.
Explanation:
In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.
Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.
This means from our definition earlier, Solid A will have a higher specific heat that solid B.
An ionic compound is a chemical compound of ions held together by electrostatic forces termed ionic bonding
EXAMPLE -/Sodium chloride ,NaCl with Na+and Ci- ions
