One gram of water becomes 1671 cm³ of steam when boiled at a pressure of 1 atm.The heat of veporization at this pressure is 2256Jg^-1.What is the external work?

Half mole of an ideal monoatomic gas is heated at constant pressure of 1 atm from $20^oC$ to $90^oC$. Work done by gas close to : (Gas constant R = 8.31 J / mol. K)

গ্যাসকর্তৃক কৃতকাজ সম্পন্ন হলে নিচের কোনটি প্রযোজ্য?  

What is the work done by $0.2$ mole of a gas at room temperature to double volume during isobaric process (take $R=2 cal \ mol^{-1} K^{-1}$)

A gas is at $1\:atm$ pressure with a volume $800\:cm^3$. When $100\:J$ of heat is supplied to the gas, it expands to $1\:L$ at constant pressure. The change in its internal energy is
