Answer: I think its a hydrogen bonding
Explanation:
Answer:
Comets are composed of ice, dust and frozen gases. The core of the comet is known as nucleus which is formed of rocks and frozen gases. Coma is the atmosphere of the comet. As the comet enters the inner solar system, the coma expands due to sublimation of frozen gases. As it nears the sun, the coma extends backwards and forms a long tail. It extends backwards due to the solar wind. The charged particles from the sun take away the evaporated material and dust of the comet backwards forming tail.
As a comet approaches the Sun, it starts to heat up. The ice transforms directly from a solid to a vapor, releasing the dust particles embedded inside. Sunlight and the stream of charged particles flowing from the Sun – the solar wind – sweeps the evaporated material and dust back in a long tail.
Answer:
false
Explanation:
B. liquids.
C. solids.
D. fluids.
E. none of the above
Convection is the transfer of heat in a fluid (which can be a liquid or gas) through the movement of its particles. A fluid near a heat source will get heated, causing it to rise and exchange place with the cooler, denser fluid.
Energy transfer by convection is primarily restricted to both liquids and gases, which are both classified as fluids. Hence, the correct answer is D. Fluids.
Convection refers to heat transfer in a gas or liquid by the circulation of currents from one region to another. This happens when a fluid near a heat source gets heated, its particles move faster and spread apart, causing the fluid to become less dense. As a result, the warmer, less dense fluid rises, and the cooler, denser fluid sinks. The continuous movement of fluid in this way creates what we call a convection current, which results in the transfer of energy.

b. 16 g
c. 32 g
d. 1.204 × 1024
The correct answer is B.
1 mol O2 x 15.999 O2/ 1 mol O2 = 15.999 O2
16 O2 when rounded.
