Answer:
Conduction
Conduction moves heat through direct sub-atomic crash. A region of more prominent dynamic energy will move nuclear power to a region with lower active energy. Higher-speed particles will crash into more slow speed particles. The more slow speed particles will increment in motor energy subsequently. Conduction is the most widely recognized type of warmth move and happens through actual contact. Models is place your hand against a window or spot metal into an open fire.
The interaction of warmth conduction relies upon the accompanying components: temperature slope, cross-segment of the material, length of the movement was, and actual material properties. The temperature inclination is the actual amount that portrays the bearing and pace of warmth travel. Temperature stream will consistently happen from most sultry to coldest or, as expressed previously, higher to bring down active energy. Once there's warm harmony between the two temperature contrasts, the warm exchange stops.
Convection
At the point when a liquid, like air or a fluid, is warmed and afterward ventures from the source, it conveys the nuclear power along. This sort of warmth move is called convection. The liquid over a hot surface grows, turns out to be less thick, and rises.
Radiation
Thermal radiation generates from the emission of electromagnetic waves. These waves carry the energy away from the emitting object. Radiation occurs through a vacuum or any transparent medium (either solid or fluid). Thermal radiation is the direct result of random movements of atoms and molecules in matter. Movement of the charged protons and electrons results in the emission of electromagnetic radiation.
Answer:
Ka = 0.16
Explanation:
HClO₄ is a strong acid and it will dissociate completely to give hydrogen ion and the conjugate base.
The pH of HClO₄ will be calculated as:
pH = -log[H⁺]
pH = -log[0.04] = 1.4
The trichloroacetic acid is a weak acid and it will not dissociate completely.
The dissociation will be:
Initial 0.05 0 0
Change -x +x +x
Equilibrium 0.05-x x x
Ka =
As pH of the acid = 1.4 it means the concentration of hydrogen ion is 0.04.
Therefore
x = 0.04
Putting values
Ka =
