On a ship sailing in Pacific ocean where temperature is \(23.4^{ \circ }C\) , a balloon is filled with 2L air. What will be the volume of the balloon when the ship reaches Indian ocean, where temperature is  \(26.1^{ \circ }C\) ?

An iron cylinder contains helium at a pressure of 250 KPa at 300 K. The cylinder can withstand a pressure of \(1\times { 10 }^{ 6 }Pa\) . The room in which cylinder is placed catches fire. Predict whether the cylinder will blow up before it melts or not (mp of the cylinder = 1800 K).

Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the gas particles. The critical temperature of ammonia and carbon dioxide are 405.5 K and 304.10 K respectively. Which of these gases will liquify first when you start cooling from 500 K to their critical temperature?

Rainy season brings lots of happiness as well as lots of diseases also.Malaria, dysentery, jaundice are common diseases that occurred in this season.Children usually get affected by these diseases.Renu's teacher advised the class to drink boiled water.She also explained to test jaundice by doing a simple test based on the property of surface tension.She told them to take the urine sample in a glass and sprinkle the sulphur powder over it.If it floats, the test is negative but if it sinks, it is positive.After reading the above paragraph, answer the following questions.
What is the reason that sulphur powder floats if the test is negative but it sinks if it is positive?

What values are expressed in the above paragraph.

Tea or coffee is sipped from a saucer when it is quite hot.

A large flask fitted with a stop-cock is evacuated and weighted; it mass is found to be 134.567g. It is then filled to a pressure of 735 mm at 31^oC with a gas of unknown molecular mass and then reweighted; it mass is 137.456 g. The flask is then filled with water and weighed again; its mass is now 1067.9 g. Assuming that the gas is ideal, calculate the molar mass of the gas.

Density of a gas is found to be 5.46 g/dm³  at 300 K and 2 bar pressure.What will be its density at STP?

A gaseous mixture containing 50 g of nitrogen and 10 g of oxygen were enclosed in a vessel of 10 L capacity at 27^oC. Calculate The number of moles of each gas.
