Physical property is defined as a property that can be observed without changing the matter into another type of matter.
<h3>What are physical properties of matter?</h3>
Physical properties of matter are those properties which can be easily observed without a change in the composition of the substance,
Some physical properties of matter include:
- Volume
- Shape
- Density
- Taste
- Color
- Mass
- Electrical conductivity
In conclusion, physical properties do not change the composition of matter and can easily be observed.

You can make sure there's no change in volume by keeping
your gas in a sealed jar with no leaks. Then you can play with
the temperature and the pressure all you want, and you'll know
that the volume is constant.
For 'ideal' gases,
(pressure) times (volume) is proportional to (temperature).
And if volume is constant, then
(pressure) is proportional to (temperature) .
So if you increase the temperature from 110K to 235K,
the pressure increases to (235/110) of where it started.
(400 kPa) x (235/110) = 854.55 kPa. (rounded)
Obviously, choice-b is the right one, but
I don't know where the .46 came from.
Answer:
106.25 m
Explanation:
Acceleration a = force / mass
= 40 / 80 = 0.5 m /s²
initial velocity u = 20 m /s
a = 0.5 m /s²
time t = 5 s
displacement s = ?
s = ut + 1/2 a t²
= 20 x 5 + .5 x .5 x 5²
= 100 + 6.25
= 106.25 m .
