In a data table, units of measurement should be shown in the headings of
columns. The unit of measurement would appear first fully spelled out
(for example, Watt) and then an abbreviated version to be used in the
data will come afterwards, either after a forward slash or within
brackets (for example, /w or (w)).
Answer:
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.
Explanation:
Answer : The heat energy needed would be, 6486.5125 J
Explanation :
To calculate the change in temperature, we use the equation:

where,
q = heat needed = ?
m = mass of aluminum = 223 g
c = specific heat capacity of aluminum = 
= change in temperature
= initial temperature = 
= final temperature = 
Putting values in above equation, we get:


Therefore, the heat energy needed would be, 6486.5125 J
First off, we can find the volume that need to be filled:
2-1.25
=0.75L
Asbthe unit is still in Litres,we need to converge it to mL.
1L = 1000mL
mL needed:
=0.75×1000
=750mL
Therefore the answer is 750mL.
Hope it helps!
Answer: B is a gas because its volume is less than the volume of the containers.
