The temperature dropped 15 degree celsius in the last 30 days. If the rate of temperature drop remains the same, how many degrees will the temperature droop in the next ten days?

Following number line shows the temperature in degree celsium ("^@C) at different places on a particular day. Observe this number line and write the temperature of the places marked on it.

Following number line shows the temperature in degree celsium ("^@C) at different places on a particular day. What is the temperature difference between the hottest and the coldest places among the above?

A radioactive element gets spilled over the floor of a room. Its half-life period is 30 days. If the initial activity is ten times the permissible value, after how many days will it be safe to enter the room ?

At Sringar temperature was -5^@C on Monday and then it dropped by 2^@C on Tuesday. What was the temperature of Srinagar on Tuesday? ON Wednesday it rose by 4^@C. What was the temperature on this day.

An oxygen cylinder of volume 30 litres has an intial gauge pressure of 15 atm and a temperature of 27^(@)C . After some oxygen is withdraw from the cylinder, the gauge pressure drops to 11 atm and its temperature drops to 17^(@)C Estimate the mass of oxygen taken out of the cylinder (R=8.31"Jmole"^(-1)K^(-1),"molecular mass of" O_(2)=32 "unit").

In general it is observed that the rate of a chemical reaction doubles with every 10 degree rise in temperature. If the generalization holds good for the reaction in the temperature range 295 K to 305 K, what would be the value of activation energy for this reaction ? [R = 8.314 mol^(-1)JK^(-1)]
