What happens to the thermal energy the particles in steam have when it comes into contact with your skin?
In general, when a hot object comes in contact with a cold object, heat (thermal energy) is transferred from the hotter to the colder object.
Analyze the following sentences. Write true if the statement is correct or false if it's not.1. Friction is the force that is present whenever to surfaces are in contact?
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another
What is the difference between emitting and reflecting?
reflected light comes from smooth surfaces such as mirrors
What type of force is tension?
There are 2 types of forces. such- Contact forces and non contact forces. Tension force comes under contact force.
What type of force is a tension forcew?
There are 2 types of forces. such- Contact forces and non contact forces. Tension force comes under contact force.
How is friction formed?
Scientists are not completely sure what causes friction; however, it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.
What does your immune system form when it comes in contact with an allergen?
antibodies are formed when the immune system comes in contact with the allergen.
How does grease lubricate the surfaces it comes in contact with?
It allows contact parts to glide against each other with minimal friction.
What can cause bumps where your urine comes out?
Infections like warts and herpes can cause bumps where the urine comes out (that is, around the urethral opening).
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by reg?
Because in contact the rock actually comes in contact with magma, this joins with the rock, so when it cools and become igneous rock, it's denser. In regular, or regional, the rock is formed from intense heat and pressure, but does not actually come in contact with magma.
What happens when an atom that looses an electron comes in contact with an atom that has gained an electron?
An ionic molecule is formed.
Why would a plant have water on the underside of its leaves?
to prevent direct sunlight from reaching it

Explain what is meant by a food contact surface?
Surface that touch food are called "food contact surfaces".
What happens when a hydrogen atom with a charge of plus 1 comes in contact with a chlorine atom with a charge of-1?
HCl is formed.
What kind of bond is eventually formed when a chlorine atom comes into contact with another chlorine atom?
Nonpolar Covalent Bond
Under what conditions will dew not form?
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
