During thermal expansion what happens to the density of a substance?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
What will happen to gas pressure when the volume is decreased?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
It is nearly impossible to solids and liquids?
Compress. They tend to occupy a nearly fixed volume.
What is the volume of sugar and water mixture?
The volume of a sugar and water mixture is less than the volume of each substance alone because when water is added to sugar, water fills in the little spaces between the particles of sugar, resulting in a lower volume.
What happens when the pressure of gas is decreased?
volume increases
Two states of matter that occupy a definite volume?
Liquids and solids are the states of matter that occupy a definite volume. Gases have neither a definite volume nor shape.
The volume of a gas is reduced when the temperature is decreased?
When the temperature of a gas is decreased, the average kinetic energy of the gas molecules decreases, causing them to slow down and come closer together. This results in a reduction in the volume of the gas since the gas molecules occupy less space.
Does the nucleus occupy most of the volume in the atom?
No it does not.
Why does air occupy more space when heated?
When air is heated, its molecules gain kinetic energy and move faster, causing them to spread out and occupy more space. This increase in volume is due to the expansion of air molecules as they collide with each other and the walls of their container, leading to an increase in pressure and volume.
Why does kid with acute bronchiolitis has delayed capillary refill?
Decreased oral fluid intake, decreased fluid volume, decreased circulating volume, decreased supply and perfusion to peripheries to maintain vital organ requirements
What volume will 3.56 moles of methane occupy at STP?
This volume is 79,79 litres.
Does solid have definite?
Yes they occupy a definite volume
Is the volume of resulting sugar mixture equal more than or less than the sum (20 ml sugar 50 ml water ) of the volumes of the unmixed sugar and water?
The volume of the resulting sugar mixture will be equal to the sum of the volumes of the unmixed sugar and water. This is because when you mix sugar and water, they do not create or destroy volume - they only mix together to occupy the combined space.
What is the density of a substance if 73.8g of it occupy a volume of 85.1mL?
The idea is to divide mass by volume.
What volume (in liters) does 2.895 mole of oxygen occupy at STP?
The volume is 64,8 L.
What volume will 15 g of NH3 occupy at stp?
The volume of ammonia is 19,5 L.
