Explanation:
the gas is changing because of the torch being lit inside the hot air balloon which make the volume change when the hot air balloon get put up
Answer:
The volume of car having density 3 g/mL and mass 75 g is 25 mL.
Explanation:
Given data:
Volume of car = ?
Density of car = 3 g/mL
Mass of car = 75 g
Solution:
The given problem will be solved through density formula.
Density:
Density is equal to the mass of substance divided by its volume.
Formula:
D=m/v
D= density
m=mass
V=volume
Now we will put the values in formula.
3 g/mL = 75 g/ v
v = 75 g/ 3 g/mL
v = 25 mL
The volume of car having density 3 g/mL and mass 75 g is 25 mL.
