Answer: Option (d) is the correct answer.
Explanation:
At high temperature, there will be more collision between the molecules as a result more energy will generate. Thus, a wave can move quickly.
In case of solids, the particles are held more closely with each other. Therefore, when temperature is high then solid particles being closer can pass on the energy more quickly as compared to gases.
Thus, we can conclude that waves move fastest in high-temperature solids.
No. It must reach the minimum threshold energy. Since its only half, there isn't enough energy for the electron to jump to the 2s energy level.
Side note: An electron can only jump between energy level if the minimum energy is met. If the energy of the photon does not meet this energy level and is below, the electron will not jump to the new level.
The answer is homogeneous mixture
Answer is: Increased pressure would increase the rate of forming water vapor.
According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products (water waper) of chemical reaction increase, if:
1) decrease temperature, because this is exothermic reaction (ΔH is negative).
2) increase concentration of reactants (oxygen and hydrogen).
3) increase pressure of the system, so reaction moves to direction where is less molecules.
Answer:
texture
Actually, texture is defined as the physical composition of something, or the look and feel of fabric.
Explanation:
An example of texture is the smooth feeling of satin.
