The principle of pressure cooker is
Boiling Point of water increases with increase in pressure
Boiling Point of water decreases with increase in pressure
Boiling Point of water increases with decrease in pressure
Boiling Point of water is not affected by change in pressure
The clinical thermometer is marked from
90oF - 115oF
95oF - 110oF
100oF - 180oF
0oF - 100oF
The physical quantity that describes the degree of hotness or coldness of a body is called
Pressure
Density
Temperature
Humidity
The corresponding Celsius scale temperature for 107o F is
42.34o C
37o C
41.67o C
40.76o C
The size of a body is not constant. It depends on
Gravity
Air
Light
The instrument used to measure the temperature is
Barometer
Calorimeter
Hygrometer
Thermometer
The standard temperature of pure melting ice at normal atmospheric pressure is taken as
Lower Fixed Point
Upper Fixed Point
Triple Point
Boiling Point
Which of the following show the highest expansion rate?
Solid
Liquid
Gas
Semi solids
The mode of heat transfer from a hot region to cold ones, without the help of an intervening medium is called
Condensation
Radiation
Transmission
Convection
If we touch on a cold body
Our body takes up heat from it
It takes away heat from our body
No heat transfer occurs
The object becomes charged
