75. ANS:
During a physical change, a material may change its shape or state, but it keeps its identity.
During a chemical change, one type of matter changes to produce one or more different types of matter.

76. ANS:
Qualitative properties are those that you can observe directly with your senses. Quantitative properties are
those that you can measure or describe with a numerical value.
Examples will vary. Possible examples are:
Qualitative: colour, odour, shape
Quantitative: temperature, melting point, boiling point

77. ANS:
Baking a cake is a non-reversible chemical reaction. The ingredients are changed into other materials with
properties that are different from the properties of the original materials.

78. ANS:
In a solid, the particles are packed closely together and do not move (but they rotate and vibrate). This is why
a solid keeps its shape in any container.
In a gas, the particles have large spaces between them and are able to move from one place to another. This is
why a gas take up the shape of the container it is in.
