Physics Chemistry & Biology Test 5
Transfer of heat of an object from hotter end to colder end is known as
Explanation: Conduction is the transfer of heat within an object or between objects in direct contact, from the hotter end to the colder end.
Cool air moving towards sea is
Explanation: A land breeze occurs when cool air from the land moves toward the sea, typically at night, as the land cools faster than the sea.
Temperature is measure of degree of ?
Explanation: Temperature measures the degree of hotness or coldness of an object. It indicates the amount of thermal energy present in the object.
Good conductor of heat and electricity ?
Explanation: Silver is a good conductor of both heat and electricity, outperforming many other materials in both areas. Diamond, on the other hand, is an excellent conductor of heat but a poor conductor of electricity.
On heating of metal, which area of expansion is more ?
Explanation: When a metal is heated, its volume expands more than its area or diameter. This is because thermal expansion affects all dimensions of the object, and volume expansion occurs in three directions (length, breadth, and height), making it greater compared to the linear or area expansion.
Mercury is also known as ?
Explanation: Mercury is commonly known as "Quick Silver" due to its silvery appearance and its liquid state at room temperature, which gives it a "quick" or flowing nature.
Which of the following is used to measure temperature of bed of the sea ?
