AC Temperature 16 se 30°C hi kyu hota hai? | #factstarshorts #youtubeshorts #shorts #ytshorts

A body cools from 70^(@)C to 50^(@)C in 6 minutes when the temperature of the surrounding is 30^(@)C . What will be the temperature of the body after further 12 minutes if coolilng proseeds ac cording to Newton's law of cooling ?

A liquid contained in a beaker cools from 80^(@)C to 60^(@)C in 10 minutes. If the temperature of the surrounding is 30^(@)C , find the time it will take to cool further to 48^(@)C . Here cooling take place ac cording to Newton's law of cooling.

Assume that one early morning when the temperature is 10^(@)C a driver of an automobile gets his gasoline tank which is made of steel, filled with 75 L of gasoline, which is also at 10^(@)C Durign the day, the temperature rises at 30^(@)C how much gasoline will overflow ? (Given, alpha for steel = 1.2 xx 10^(-5)"^(@) C^(-1),gamma for gasoline = 9.5 xx 10^(-4)"^(@)C)

Assume that one early morning when the temperatures in 10^(@)C, a driver of an automobile gets his gasoline tank which is made of steel, tilled with 75 L of gasoline, which is also at 10^(@)C. During the day, the tempaerature rises to 30^(@)C, how much gasoline will overflow ? (Given, alpha for steel =1.2xx 10^(-5)"^(@)C^(^1), gamma for gasoline =9.5xx10^(-4)"^(@)C^(-1))

Three liquids A,B,C have initial temperature 10 deg C, 20 deg C and 30 deg C resp. A and B are mixed then temperature of mixture is 16 deg C. If B and C are mixed then temperature of mixed is 26 deg C. If A and C are mixed the temperature of mixture is

A sample of an ideal gas is taken through the cyclic process abca shown in Fig.21-33. The scale of the vertical axis is set by p_b = 7.5 kPa and p_(Ac ) = 2.5 kPa. At point a, T = 280 K. (a) How many moles of gas are in the sample? What are (b) the temperature of the gas at point b, (c) the temperature of the gas at point c, and (d) the Higure 21-33 Problem 30. net work done by the gas during the cycle, and (c) the net energy added to the gas as heat during the cycle?
