Why is heating a liquid affects its viscosity?
The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.
Which reason best explains why plasmas are good conductors?
We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity. Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.
What is the lowest energy state of condensed matter?
The particles that make up a solid have the lowest energy, and vibrate in place. This results in the characteristics of a solid, such as a definite shape and volume. A solid is actually the frozen state of matter for a substance. A substance does not have to freeze at a cold temperature.
What are thermal plasmas?
A thermal plasma is in thermal equilibrium, which is to say that the temperature is relatively homogeneous throughout the heavy particles (i.e. atoms, molecules and ions) and electrons.
Why a plasma based light does not have a high temperature?
They have mobile charged particles. Temperature depends on the average kinetic energy of the particles in a sample. How does this help with explaining why a plasma-based light does not have a high temperature? Most particles in the plasma are heavy and slow.
Which state of matter has particles with the least energy?
Solid
Can you use baking soda to put out a grease fire?
If a grease fire starts: Cover the flames with a metal lid or cookie sheet. If it’s small and manageable, pour baking soda or salt on it to smother the fire. As a last resort, spray the fire with a Class B dry chemical fire extinguisher. Do not try to extinguish the fire with water.
Does salt put out fire?
Salt will smother the fire almost as well as covering it with a lid, while baking soda chemically extinguishes it. But you’ll need a lot of each–toss on handfuls with abandon until the flame subsides. Avoid using flour or baking powder, which can explode in the flames instead of snuffing them out.
Can you use flour on a grease fire?
Do NOT use flour on a grease fire. While sometimes baking soda can extinguish a small grease fire (though not if the fire is too overwhelming), flour cannot and should not be used. Due to chemical risk of contaminating your kitchen, putting out a grease fire with your fire extinguisher should be the last resort.
