a difference in density between gases creates buoyancy, which is the ability of an object to float. At 0 degrees celsius, helium

has a density of 0.18kg
Chemistry

Answer: for an object or gas or liquid to float in another there must be a difference in density

Explanation:

Helium has a density of 0.18 kg/m³ and air has a density of 1.29 kg/m^³. If a balloon is filled with helium it will float in air due to density differences

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces

How electron infinity depends upon nuclear force of attraction​
almond37 [142]

Answer:

There are two factors that can affect electron affinity. These are atomic size and nuclear charge. ... The smaller the atom is, the closer the outermost shell is; therefore, it is a stronger attraction between the nucleus and the incoming electron. That means the electron affinity is higher for smaller atoms.

A gas has a volume of 590 mL at a temperature of -55°C what volume will the gas occupy at 30°C
Ipatiy [6.2K]
Using ideal gas formula (PV=nRT), you can conclude that volume directly related to the temperature. That means an increase in temperature will cause an increased volume too. Note that the temperature is using Kelvin, not Celsius. The calculation would be:

V1/T1= V2/T2
590ml / (-<span>55+ 273)K = V2/ (30+273)K
V2= (590ml/ 218K) * 303K
V2= 820ml</span>
