Answer:
The answer would be C 214g
Explanation:
890j of heat causes 4.6°c increase in temperature
specific heat of aluminium after is o.9022 j /g°c
now by using the formula .The mass of aluminium would be c that is 214 g
Answer: D
Explanation:
A control group is the variable that remains constant throughout the whole experiment
This is what my teacher did (example). So if the weight was 40.5 and the volume was 15.0:
<span>
d = 40.5 g / 15.0 mL (that means you divide it)d = 2.70 g/mL
