What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
What happens when something reaches absolute zero?
What happens when something reaches absolute zero? At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values. What determines the state of […]

What happens to the molecules of water when it freezes?
What happens to the molecules of water when it freezes? Point out that when water freezes, the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were in liquid water. Note: The molecules in ice […]

What happens if you block potassium channels?
What happens if you block potassium channels? Activation leads to an increase in conductance and the termination of action potentials, hyperpolarization, and a reduction in excitability. Conversely, a block of the channels leads to depolarization, prolongation of action potentials, repetitive firing, and increases in transmitter release and endocrine activity. What happens if potassium leak channels […]
Do polar molecules have to be asymmetrical?
Do polar molecules have to be asymmetrical? Polar molecules MUST have an asymmetrical structure to be polar, because symmetry cancels out net charge. Asymmetrical molecules are always polar. Symmetrical molecules can be polar and non-polar. Polarity is dependent on the difference in electronegativity of the molecule’s atoms and shape. What is an example of asymmetrical? […]
Why must the transfer of metal be done quickly?
How do you overcome lack of physical activity?
How do you overcome lack of physical activity? Social support Explain your interest in physical activity to friends and family. Ask them to support your efforts. Invite friends and family members to exercise with you. Plan social activities involving exercise. Develop new friendships with physically active people. What physical activity is the least expensive? Walking […]
