Answer:
ridgid, fixed shape, and fixed volume
Explanation:
solid are all the thing listed as the answer because, you should know solids are not bendable. Therefore they must be very hard.

Answer:
No. The student is wrong.
Explanation:
Concentration of solution = mole/volume
mole of 5 g of copper = 5/63.546 = 0.0787 mole
Concentration of A = 0.0787/0.05 = 1.57 M
mole of 10 g of copper = 10/63.546 = 0.1574 mole
Concentration of B = 0.1574/0.1 = 1.57 M
The two solution are added together:
Total concentration = total number of mole/total volume
= 0.0787 + 0.1574/0.05 + 0.1
= 0.2361/0.15
= 1.57 M
Hence, the new solution has the same concentration with solution A and solution B.
The student's conclusion was wrong.
They all have something to do with heat
