Why are steam burns more serious than burns caused by an equal amount of equally hot water? Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization.

What causes the attractive forces between particles in matter?
What causes the attractive forces between particles in matter? The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together. What […]
Why do you set the altimeter?
Why do you set the altimeter? Weather changes that affect temperatures and air pressures cause the complications in understanding and using an altimeter. This is why an aircraft’s actual height above mean sea level is its true altitude while what the altimeter says is the indicated altitude. Before going flying, you have to set the […]
