Because they use high temperature to ionize the element. Temperatures mostly ionize if not all elements exist as a gas.
Answer:
- <em>Stored chemical energy is converted to mechanical energy.</em>
Explanation:
A <em>battery</em> posses <em>chemical energy</em>: this is chemical potential energy, which means that it is stored in the chemical bonds of the compounds in the battery. When the compounds in the battery react some bonds are broken and others are formed; at the end some energy is released and electricity is produced.
So, the chemical energy is first transformed into electrical energy.
A motor in the toy is able to transform that electrical energy into motion of gears and axes, which is how the wheels can spin. This motion of gears, axes and wheels is mechanical energy (kinetic energy).
Then, as you see, in that way the stored chemical energy in the battery is transfered to mechanical energy of the toy as it <em>rolls across the floor</em> thanks to the spin of the wheels.
Answer:
Postulate: Gas particles are extremely small and are far apart.
The activities can be used to demonstrate the postulate is :
<u>Observing colored gas spreading into an inverted jar placed on top of a jar containing the gas</u>
<u />
Explanation:
colored gas spreading into an inverted jar placed on top of a jar containing the gas:
This occur because of two reasons:
1. <em><u>The Gaseous particles are largely spaced . There is large distance between the gases molecule</u></em>
<em><u>2. The gases are in continuous motion . Hence they posses very high kinetic energy . This is the reason they mixes quickly if placed in a jar.</u></em>
<em><u>This occur by the process of diffusion. </u></em>
Diffusion of Gases: The intermixing of particles from the region of high concentration to low concentration.
The coloured gas goes into the space between the gaseous molecule present in the jar.(Gases are far apart)
As soon as the coloured gas is mixed in the jar , It spread quickly by diffusion because , The gaseous particles are extremely small and are far apart.
Answer:
333N
Explanation:
Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.7m/s2, we multiply the object's mass by this quantity to calculate an object's weight on mars.
So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.
The way its structured is they're layered on top of each other and because of that it has a much faster charge rate
