760cm3-474cm3 286cm3 is the change in volume. To get the rate you will need to divide this change in volume by the time it takes for the volume to shrink. If, for example, the change took 30 minutes then the shrink rate would be 286cm3/30 min or about 9.533 cm3/min.
If you cool a gas then its volume shrinks. As the container is expand/contactable, the container will also shrink.
Cold air contracts and becomes denser, so it tends to shrink in volume. This is why inflated objects like balloons or tires appear to deflate in cold weather.
If you shrink the container containing gas, the volume of the gas decreases because the gas particles are forced into a smaller space. This increase in pressure due to the reduced volume is described by Boyle's Law.
They don't. Some liquids expand when they become solid and others shrink, while some do maintain the same volume.
Cells can shrink due to dehydration, loss of nutrients, or exposure to hypertonic solutions (higher solute concentration outside the cell). This causes water to move out of the cell, leading to a decrease in cell volume.
The volume of air inside the balloon will decrease as the temperature drops in the refrigerator, causing the balloon to slightly shrink. When the balloon is taken out of the refrigerator and warms up, the air inside will expand again and the balloon will return to its original size.
It decreases. The colder air contracts, making the balloon shrink.
Balloons can shrink due to loss of gas inside, typically helium or air, escaping through small holes or pores in the balloon material. Changes in temperature can also cause the gas inside the balloon to contract, reducing its volume and making the balloon appear to shrink.
The decrease in the volume of an object as it cools is called thermal contraction. This occurs because as the temperature decreases, the particles in the object slow down, reducing the space between them and causing the object to shrink in volume.
First, you must decide whether with "size" you mean the diameter (or equivalently the radius), or the volume. Assuming you mean the volume, an ideal gas will shrink to half the volume if the temperature is reduced to one-half, so that might be a good approximation. However, the temperatures must first be converted to Kelvin. (If you mean the diameter, for the diameter to get reduced to 1/2 the original diameter, the volume would get reduced by 1/8 of the original volume).
Will shrink.
