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.
How would air particles in a balloon at 0 C compare to air particles in a balloon at 100 C?
The individual molecules will be moving faster at 100 °C, than at 0°C. The molecules would also be further apart (ie. they would occupy a larger volume).
It is nearly impossible to solids and liquids?
Compress. They tend to occupy a nearly fixed volume.
What happens when the pressure of gas is decreased?
volume increases
When water boils it becomes steam its particles spread out and occupy a greater volume has its density increased or decreased?
When water boils and turns into steam, its particles spread out, occupying a greater volume. As a result, the density of steam is decreased compared to liquid water, because density is defined as mass per unit volume, and the same mass of water now occupies a larger volume as gas.
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.
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.
When two materials are mixed the volume of the mixture is between those of the separate materials?
When two materials are mixed, the total volume of the mixture can often be less than the sum of the individual volumes due to a phenomenon called "volume contraction." This occurs because the molecules of the two materials can occupy the same space more efficiently when combined, leading to a reduction in overall volume. However, in some cases, particularly with materials that do not interact well, the volume of the mixture may be greater than the sum of the individual volumes. Thus, the final volume of the mixture depends on the properties of the materials involved.
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.
Does the nucleus occupy most of the volume in the atom?
No it does not.
What volume will 3.56 moles of methane occupy at STP?
This volume is 79,79 litres.
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
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.
