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.
Answer:
answer it by yourself and own way
Answer:
I hope this helps, sorry if it doesnt. Not really good with chemistry, hope you have a great day/night :}
Explanation:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance.
12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
Answer: The given statement is true.
Explanation:
It is known that due to increase in temperature ice melts. Therefore, during ice age there is also melting of ice and solid state of water changes into liquid state of water.
Therefore, this water moves from its initial place and changes its position result in the change of land and specific areas.
Thus, we can conclude that the statement during an ice age, land can move and specific areas can be permanently changed is true.
Answer:
Answer below
Explanation:
Physical changes dont change the chemical makeup of an object. An example would be to tear a piece of paper. Tearing the paper doesnt change how the paper was made chemically
Chemical changes on the other hand do change the chemical makeup of an object. An example of a chemical change would be to bake a cake. The reason being that the chemical makeup of the cake batter is changed so that the actual cake is formed.
