Walk out. If it's denser than air, it'll settle to the bottom
Answer:
A
Explanation:
Pressure, temperature are measurable properties and they are also known as physical properties.
Mass = 0.201kg
Energy = 15J
temperature change = 10C
Energy(E) = mass(m) × specific heat capacity(c) × temperature change(θ)
we can rearrange this to make specific heat capacity the subject
c =

c =

c =7.46268657
