Answer: A. Endothermic
Explanation:
In an endothermic reaction, heat is sucked in from the surrounding area by the reactants so that they may use it to react and form new products. This will therefore reduce the temperature in the said surrounding by the amount that the reaction needed.
This is what ice does when it melts. It sucks in the heat surrounding the area and then melts but leaves the area colder. For instance, putting ice in water ensures that the ice melts but because it sucked in the heat from the water to do so, the water gets colder as a result.
Meteor is the flash of light caused rock debris we see from space.
Meteoroid is the debris.
Meteorite is the debris that lands on earth.
Answer: Option (D) is the correct answer.
Explanation:
When heat or energy is transferred through the space in the form of waves or through a material medium then it is know as radiation.
For example, when we take Sun bath then our body gets warm due to solar radiation.
For transfer of heat through radiation it is not necessary that the objects have to in contact with each other.
Thus, we can conclude that out of the given options, the transmission of heat without any contact.
Henry's Law is written in equation as:
C = kP
where
C is the concentration
k is the Henry's law constant
P is the partial pressure
This law is applied to soluble gases in liquids. At a certain temperature, there is a specific value of the Henry's Law constant. The C represents the solubility. Hence, we solve for C.
C = (<span>6.26×10</span>⁻⁴ <span>mol/(L⋅atm))*(2.85 atm)
C = 0.0017841 mol/L</span>
