Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.
Solids can be hard like a rock, soft like fur, a big rock like an asteroid, or small rocks like grains of sand. The key is that solids hold their shape and they don't flow like a liquid.

Answer:
Explanation:
100 W bulb is using energy of 100 J in one second.
22 percent of the electrical energy is transformed to radiant energy.
a )
So , electrical energy is transformed to radiant energy per second
= 100 x .22 = 22 J
energy transformed in one minute = 22 x 60 J
= 1320 J
b )
electrical energy is transformed to heat energy per second
= 100 x .78 = 78 J
energy transformed in one minute = 78 x 60 J
= 4680 J
