Question

1) Explain the meaning of following statements
a) Boiling point of water is 100℃.
b) 9 W LED is glowing.
c) Pressure exerted by an object is 1 pascal.

Answer 1

Answer:

a) Boiling point of water is 100℃.-A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude.

b) 9 W LED is glowing.-If the bulb continues to glow weakly after removal, it is due to the luminescent layer or the LED driver. However, if the lamp goes out immediately when it is removed from the socket, the cause must be found in the electrical installation.

c) Pressure exerted by an object is 1 pascal.-When a force of 1N acts on an area of 1m2, the pressure exerted is equal to one pascal.
