Convert - 102 C ∘ in Kelvin.

Given T ° C = - 102 ° C Temperature conversion formula is: C 5 = F - 32 9 = K - 273 5 So, the formula used: T ( K ) = T ( ∘ C ) + 273 = - 102 + 273 = 171 K

The pressure of a gas at S.T.P is tripled when temperature is raised to 546 C ∘ . What will be the change in volume?

S.T.P. are the standard temperature and pressure condition. The standard temperature is 273 K ( 0 ∘ Celsius) and the standard pressure is 1 atm Pressure. At S.T.P, one mole of gas occupies 22 . 4 L Of volume (molar volume). Given : Pressure P 1 = 1 atm Volume V 1 = 22 . 4 L Temperature T 1 = 273 K Pressure P 2 = 3 ( P 1 ) = 3 × 1 = 3 atm Temperature T 2 ( K ) = 546 + 273 = 819 K To find: Volume V 2 = ? Formula used: P 1 V 1 T 1 = P 2 V 2 T 2 Calculation: 1 × 22 . 4 273 = 3 × V 2 819 V 2 = 1 × 22 . 4 × 819 3 × 273 V 2 = 22 . 4 L

Diffusion is the process of movement of molecules under a concentration gradient. It is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient. It mostly happens in liquids and gases because their particles move randomly from place to place.
