Answer: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.
Explanation:
The correct answer is (3)
I-131 and P-32
The explanation:
according to attached table:
- we can see that the half life of p 32 is 14.28d (more than one hour)
- and the half life of I-131 is 8.021 d
(more than one hour)
and They both have β- decay mode and with half-lives greater than hour.
Example:
sample density of gasoline, 20 g of weigth into 5 <span>mL
Answer:
D = m / V
D = 20 g / 5 mL
D = 4 g/mL</span>
