Would you expect larger or smaller molecules to be components of a more viscous liquid?
Larger molecules make a liquid more viscous. Larger molecules occupy more space compared to smaller molecules which makes a liquid thicker.
How are velocity and temperature related?
By changing the temperature of the liquid (an object is dropping in) the velocity is likely to increase as the temperature increases because by increasing the temperature of the liquid, the result would be that the object's velocity will increase.submittted by munchez :-)
How is terminal velocity reached?
This is an interesting situation. First of all we have to understand the nature of forces possible acting on the drowning body in a liquid medium. 1) weight of the body Mg acting always downward 2) buoyant force which equals to the weight of the displaced liquid always acting upward opposite to weight of the body. 3) As the weight Mg is more than buoyant the body there is net downward force which makes the body accelerated within the liquid medium hence sets in motion. 4) now due to movement of body in the liquid there comes the viscous drag due to viscous nature of liquid. Viscous drag is always opposite to the direction of motion of body in the liquid. More beautiful point is that this viscous drag ,according to Stokes's formula, is proportional to the speed of the body. Hence viscous drag gradually increases. At one stage the upward viscous drag becomes exactly equal to the net downward force. So now no force is acting on the already moving body. By Newton's first law of motion, every body continues in its uniform motion unless compelled by any external force. Hence uniform motion there after. So maximum velocity which is named terminal velocity. Very interesting scientific explanation! Isn't it?
Is the density of gaseous substance likely to be larger or smaller then the density of liquid or solid substance at the same temperature and why?
Temperature in this instance will not affect density, but rather pressure. The density of the gas will be much smaller than the density of a liquid or solid of the same chemical because it is a gas. The formula for density is mass over volume, and a gas has no measurable mass, making the gas always less dense than the liquid and the solid.
What is the standard value of velocity and wavelenght of ultrasonic waves in benzene?
The standard value of velocity of ultrasonic waves in benzene liquid is 1260 m/sec.
When a pearl is dropped into a dense liquid it quickly acquires a uniform non accelerated motion downward why does this happen?
It accelerates quickly up to a low terminal velocity, then continues at constant velocity. At terminal speed, the downward force of gravity and the upward force of liquid resistance are in balance.
What is the name of an object in free fall?
Terminal velocity. It is when something falls through a gas or liquid it accelerates, at a decreasing rate, until it reaches its maximum constant velocity.
The greatest velocity a falling object reaches?
The greatest velocity that a falling object can achieve is termed, terminal velocity. The equation for terminal velocity is equal to the square root of (2mg / (air density * projected area * drag coefficient))
Would you expect larger or smaller molecules to be components of a more viscous liquid?
Larger molecules make a liquid more viscous. Larger molecules occupy more space compared to smaller molecules which makes a liquid thicker.
What do you call a measure of liquid?
The measure of a liquid is its volume. Volume is measured in litres, smaller volumes are millilitres, and larger are cubic metres.
Why do cracks in a rock get bigger if water freezes in them?
Frozen water molecules are larger and expand. In liquid form H2O is smaller
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
How are velocity and temperature related?
By changing the temperature of the liquid (an object is dropping in) the velocity is likely to increase as the temperature increases because by increasing the temperature of the liquid, the result would be that the object's velocity will increase.submittted by munchez :-)
That a larger volume of liquid will always evaporate faster than a smaller volume?
evaporation speed is determined by temperature, humidity and exposed surface area
Drift velocity in two-phase flow?
it is the relative velocity of two phase that is gas and liquid.
What happens to the volume of a substance if it changes phase from a solid to a liquid?
it inreases cause it isn't a solid hard shape and so the liquid will fill its container like ice and water. ice is smaller but water has a larger volume
