Question

5) The average density of a hot air balloon is 0.85kg/m'
The volume of this air is 2800m
(0) State the equation linking density, mass and volume.
I
(ii) Calculate the mass of hot air in the balloon.​

Answer 1

Answer:-

• Density of hot air=0.85kg/m$^3$
• Volume of air=2800m$^3$

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \qquad\quad\sf{:}\longrightarrow Mass=Density\times Volume$

$\\ \qquad\quad\sf{:}\longrightarrow Mass=0.85\times 2800$

$\\ \qquad\quad\sf{:}\longrightarrow Mass=2380kg$
