Which element was discovered by joseph priestley to be what his contemporaries called ""dephlogisticated air""?

Answers

Answer 1
Answer:

Answer:

oxygen

During his lifetime, Priestley's considerable scientific reputation rested on his invention of soda water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen).

The part of the cerebrum that controls voluntary movements is located in the _______ lobe. A. frontal B. parietal C. temporal D. occipital

Answers

The part of the cerebrum that controls voluntary movements is located in the frontal lobe of the brain.

Hence, the correct option is A.

The frontal lobe is responsible for various higher cognitive functions, including decision-making, problem-solving, planning, judgment, personality, and motor control.

It plays a crucial role in initiating and coordinating voluntary movements of the body. The primary motor cortex, which controls specific voluntary movements, is located in the frontal lobe, just anterior to the central sulcus.

Therefore, The part of the cerebrum that controls voluntary movements is located in the frontal lobe of the brain.

Hence, the correct option is A.

What environmental factors affect kinetic energy and diffusion? 

Answers

There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material. All the mentioned factors directly impact the kinetic energy and diffusion of a material or compound or fluid. Temperature can generally increase the kinetic energy of molecules within a compound or a substance. Increase or decrease of temperature changes the shape and nature of the material concerned. So these natural factors have a big influence on the kinetic energy and diffusion.



Answers
Temparature
Humidity (Amount of molecules in the air)


Explanation
Examples of environmental factors are, temperature, wind, pressure, humidity etc. Kinetic energy is the energy possessed by a body in motion. 
This motion can be affected by factors such as rain and humidity since the make the medium more dense. It require more energy to move in a denser medium. 
Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. When temperatures are high the molecules get more energy and move more faster increasing the rate of diffusion.
