Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
Decrease
What substance decreases the bodys ability to clot?
Erythrocytopenia
Which may be true for a substance that absorbs energy?
The energy decreases the molecular motion and the kinetic energy of the substance.
What is a substance that increases H and decreases pH when it dissociates in water?
An acid.
What is a black burnable substance mined from earth used for generating electricity same as charcoal?
Coal
WOULD A SUBSTANCE THAT DECREASES MEMBRANE PROBABILITY TO SODIUM INCREASE OR DECREASE THE PROBABILITY OF GENERATING A NERVE IMPULSE?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
Would a substance that decreases membrane permeability to sodium increase or decrease the generating of a nerve impulse?
Decrease
What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
When a substance melts The temperature of the substance increases?
it decreases.
When a substance melts the temperature of the substance?
it decreases.
When a substance is melting the temperature of the substance what?
it decreases.
Does a solid forms when the average energy of a substance's particles decreases then increases?
Decreases.
As the density of a substance increases the volume of a given mass of that substance .?
Decreases
What is a substance that decreases activation energy?
A catalyst
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
What decreases the rate at which a substance melts?
decreasing the temperature
What substance decreases the bodys ability to clot?
Erythrocytopenia
