Warm weather is on its way, categorized by calm winds
It is cold and wet
Very unsettled weather is approaching. Categorized by strong winds and rain.
It is cold and wet but warm calm weather is approaching.
Only pulls objects towards each other.
Only acts on certain materials
Only acts over a small distance
Strength depends on many things including size and shape.
A force that attracts and repels
Has a stronger force on smaller objects
Acts on all objects
Can act over very large distances (many millions of kilometers)
6 carbon atoms and 12 water molecules
6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms
6 chlorine atoms, 12 helium atoms and 6 oxygen atoms
The high pressure in the can drawing in water
The high pressure of the atmosphere crushing the weakened can
The low pressure inside the can exerting too much force.
None of the above
The rain on the metal cylinder has rusted part of the cylinder. This means it is weaker and therefore cannot hold sufficient pressure anymore.
As the man drew the cylinder next to the barbecue it has increased in temperature. This has caused the space between the gas in the cylinder to expand leading to an explosion.
As the gas is being used by the barbecue it is leading to a low pressure environment inside the cylinder leading to an implosion.
A = condensation, b = solidification, c = sublimation
A = sublimation, b = condensation, c = melting
A = sublimation, b = evaporation, c = freezing
A = sublimation, b = condensation, c = solidification
It is a physical change because the sugar has dissolved into the sulphuric acid
It is a physical change because the sugar has changed into carbon.
It is a chemical change because the sugar has been dissolved into the sulphuric acid.
It is a chemical change because the sugar has changed into carbon.
As the height of the graph increases, it increases at the same time as the altitude. Therefore as height increases, pressure increases.
As the height of the graph increases the pressure of the graph decreases. It can therefore as height increases, pressure decreases.
As the height of the graph decreases, the pressure also decreases.
None of the above answers are close to being correct.
Solids move more than liquids because their particles are closer together.
As a solid melts it must be gaining energy as it's particles move further apart.
The particles in a gas have so much energy that the bond between adjacent particles are broken.
As a liquid cools, it loses energy so the particles come closer together and move less.
As the solid turns into a gas, the gas takes up more room than the solid creating an area of low pressure. The bullet is therefore "sucked" out of the gun and the atmospheric air is trying to get inside the gun.
As the solid turns into a gas, the gas takes up more room than the solid creating an area of low pressure. The bullet is therefore forced out of the gun as the gas wants to get from an area of high to low pressure.
The hammer hits the bullet with such force that the bullet is propelled out of the gun
None of these answers are correct.
The balloon starts out semi-deflated so it wont rise too quickly.
If the weather balloon started out fully inflated it would pop before achieving a great height.
A weather balloon starts out semi deflated because as it climbs in the air there is less pressure so the balloon will expand.
The balloon starts out semi-deflated so it will rise quickly.
The pressure in a vacuum is zero (or very close to zero).
Sound can be heard for a long distance in a vacuum as there is no resistance.
Air will rush into a vacuum as it is an area of very low pressure.
A vacuum can be made in a lab with the aid of a vacuum pump.
Nothing. There is a flaw in the programming
The RCX will go forward at speed 3 for 2 seconds, then turn right sharply for 2 seconds before stopping
The RCX will go forward at speed 3 for 2 seconds, then turn right sharply for 2 seconds and will repeat this twice.
The RCX will go forward at speed 3 for 2 seconds, then turn right sharply for 2 seconds but will not stop as there is an ABC stop missing.
