37. The word ‘matter’ refers to everything in the universe that has mass and takes up space.
States of matter are generally described on the basis of qualities that can be seen or felt. Three
states of matter can be found in daily life: solid, liquid and gas. Matter that feels hard and
maintains a fixed shape is called a solid, matter that feels wet and maintains its volume but not
its shape is called a liquid. Matter that can change both shape and volume is called a gas.
Read the given passage carefully and give the answer of the following questions:

Q1. In which form, do the water molecules have less kinetic energy?
a. Ice b. Water c. Steam d. All of them have equal kinetic energy
Q2. Which of the following describes the liquid phase?
a. It has a definite shape and a definite volume.
b. It has a definite shape but not definite volume.
c. It has a definite volume but not a definite shape.
d. It has neither a definite shape nor a definite volume.

Q3. Which one of the following statements is wrong for gases?
a. Gases do not have a definite shape and volume.
b. Volume of the gas is equal to the volume of the container confining the gas.
c. Confined gas exerts uniform pressure on the walls of container in all directions.
d. Mass of the gas cannot be determined by weighing a container in which it is enclosed.
Q4. ‘Gases are easily compressed but liquids cannot be compressed.’ What can be inferred
from this statement?
a. The forces of attraction between gas particles are stronger than that between liquid particles.
b. The gas particles are spaced further apart than liquid particles.
c. The gas particles have less energy than liquid particles.
d. The gas particles move more rapidly than liquid particles.
38. Suppose a squirrel is moving at a steady speed from the base of a tree towards some nuts. It
then stays in the same position for a while, eating the nuts, before returning to the tree at the
same speed. A graph can be plotted with distance on the x-axis and the time on y-axis.

Observe the graph carefully and answer the following questions.(any four)
(i) Which part of the graph shows the squirrel moving away from the tree?
(ii) Name the point on the graph which is 6 m away from the base of the tree.
(iii) Which part of the graph shows that the squirrel is not moving?
(iv) Which part of the graph shows that the squirrel is returning to the tree?
(v) Calculate the speed of the squirrel from the graph during its journey.
