Answer:
solid
Explanation:
liquid can't take the shape of the container because it flows freely and it doesn't have a definite shape and it has space between it e.g water
gas also doesn't shape and e. g air
but solid takes a definite shape because it doesn't have space in between of
Answer:
We are given:
V(i) = 0.3 L V(f) = 0.36 L
P(i) = x pa P(f) = 400 pa
T(i) = T(f) = 293 k
Using the gas formula:
PV = nRT
Since n , R and T are constant,
PV = k (where k is a constant)
Hence we can say that:
P(i) * V(i) = P(f) * V(f)
x * 0.3 = 0.36 * 400
x = 14.4/0.3
x = 480 pascals
Hence the initial pressure is 480 pascals
Converting to Kpa, we have to divide by 1000
Initial pressure (Kpa) = 0.48
Gravitational potential energy is the energy stored in an object relative to its position :)
