A physical state of a substance is whether it is solid, liquid, or gas.
a change in size, shape or the state of matter is a physical change. True for A+.
The state of matter is a physical property at any temperature.
Evaporation is a physical property. It is the process by which a substance transitions from a liquid state to a gaseous state without undergoing a chemical change.
This name is chalcogens.
Colourless gas
Oxygens liquid state
A gas.
At 25 degrees Celsius, oxygen is in a gaseous state.
oxygen is a gas at room temperature
Ribose has 10 hydrogens and 5 oxygens.
The bond angle between the oxygens in SeO2 is approximately 120 degrees.
The hybridization of both oxygens in a carboxylic acid group is sp.
it has no oder .
Oxygen is in p block. it is a useful gas. oxygens atomic number is 8.
The molecular geometry of the oxygens in hydrogen peroxide (H2O2) is bent or angular.
The water leaving as steam has undergone a physical change from a liquid state to a gaseous one. No chemical change has occurred because it is still H2O.Basic explanation:H2O(liquid) + heat H2O(gaseous)Water passes from a liquid form to a gaseous form through evaporation. By definition, any change in the state of matter is a physical change.Evaporation ProcessWhen the H2O molecule is heated (excited), physical reactions occur:- excitement (disorder increase, molecules are increasingly kegeling)- breaking of the hydrogen bridges/connections between the "O" (oxygens) and "H" (hydrogens), liberating them from their attractive forces through the process of gasification.
