(D) Silver fish
Correct Answer : B
What are the changes in the molecules of an object when it is heated?
(A) the speed will increase
(B) weight will decrease
(C) the load will increase
(D) energy will decrease
Correct Answer : A
Explanation :
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
What happens to the temperature of water when it falls from a height?
(A) decreases
(B) increases
(C) neither decreases nor increases
(D) none of these
Correct Answer : B
Explanation :
The temperature of water increases when it falls from a height because when a water drop reaches the ground surface from a height, its potential energy increases.
he temperature at which ice, water and vapour remain in equilibrium is called?
(A) freezing point
(B) triple point
(C) critical temperature
(D) boiling point
Correct Answer : B
Explanation :
The technical term for this is the triple point of water since at this temperature, not only solid ice and liquid water, but also water vapor coexist. The temperature and pressure conditions that allow a substance's gaseous, liquid, and solid phases to exist in equilibrium is called triple point of the substance.
The application of low-temperature engines is?
(A) submarine propulsion
(B) research on superconductivity
(C) rocket technology
(D) frost free refrigerators
Correct Answer : C
Explanation :
Low-temperature combustion (LTC) is a recent engine technology that can reduce the oxides of nitrogen (NOx) and soot emissions simultaneously while maintaining higher thermal efficiency.
The colour of the sky appears to be blue.
(A) due to diffraction
(B) due to scattering
(C) due to reflection
(D) due to refraction
Correct Answer : B
