What is meant by dry mass?
dry mass means the mass of an object/organism once it has been dried and the water has been removed.
What describes and air mass with the symbol C T?
A cP (continental polar) air mass is generally cool and dry.
What are the difficulties in measuring growth in a living organism?
Growth in organisms is basically defined as cell division before cells become specialised. Different parts of organisms grow at different rates and different times but growth can be measured as an increase in either wet mass, dry mass or height. Height and wet mass can be measured when an organism is alive, but dry mass can only be measured when an organism is dead, because then all the water can be removed. Despite this, dry mass is the best for giving a measure of growth. Dry mass is often used because it eliminates the fluctuations that you get from using wet mass due to its water content. This is evident in weighing plants, since they have a high level composition of water and this water content depends on the amount of water in its environment so using dry weight tends to be more reliable in this case as it gives an idea of mass change.
What is meant by the term dry mass?
mass of solid matter without water.
How does mass change when solutes are added to solvents?
The mass of the whole doesn't change, it's simply the sum of the mass of the solute and the mass of the solvent.
What is dry mass?
The definition of dry mass is the mass of a biological sample after the water content has been removed. When the water is removed, the dry mass can be compared on equal terms.
What is that if its dry weight 2 kg if get wet becomes 1kg if burnt becomes 3kg?
None. The mass of an object won't change if you change the state of matter. When you burn it, the mass can change, since the atoms of the original object combine with oxygen, usually.
What is meant by dry mass?
dry mass means the mass of an object/organism once it has been dried and the water has been removed.
Does mass change with temperature change?
Mass does not change with temperature
Is a maritime tropical air mass warm and humid or dry?
dry
Does mass change in a physical change?
In this case mass doesn't change.
What is the total dry mass of an organism?
The total dry mass of an organism equals biomass. How biomass is measured depends on why it is being measured. It can be measured as the natural mass or as it is. It can also be measured in terms of dry, organic mass. And sometimes just tissues count or just bones.
What describes and air mass with the symbol C T?
A cP (continental polar) air mass is generally cool and dry.
What is an air mass that forms over a desert called?
Hot, dry and low pressure forms over hot deserts. Known as a tropical continental air mass.
Why mass is measured as dry mass?
because when it contain water the mass of water will be the one to be obtained

Why is biomass is often calculated as dry mass rather than wet mass?
Dry masses are used to work out the pyramid of biomass because the weight and density of wet mass can fluctuate. Water can disappear from the mass, causing it to lose weight. Adding more water will make it heavier and denser.
