Answer:
A. unexpected change in odor
Explanation: Common physical changes include melting, change of size, volume, color, density, and crystal form. Example the classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change.

Answer:
Explanation:
1. A measure of how quickly velocity is changing is the acceleration
Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.
It is measured in the unit m/s²
2. Speed in a given direction is the velocity
Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.
When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.
3. Force that resists moving one object against another is the friction
Friction is a force that opposes motion. It prevents a body from moving.
4. Measure of the pull of gravity on an object Weight
Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;
W = mg
W is the weight, m is the mass and g is the acceleration due to gravity
5 Tendency of an object to resist a change in motion is inertia
Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.
6 Size is the magnitude
The ground water refers to water present in the under earth in the cracks or pores or similar spaces.We majorly depends upon this sources of water specially in rural area.
It helps in irrigation and also serve as drinking water supply.
The words or phrases which identify layer of ground water are:
a) water table: the uppermost water saturated layer
b) kettle lake: it is an underground lake (not ground water)
c) Saturation zone : this is the zone of water below the water table
d) undergound lake: this is kettle lake (not ground water)
e) sink hole: Not a layer of ground water
So the layers of ground water are
a) water table
b) saturation zone
