No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
False. Pressure decreases from the center to the outside.
False
False. Addition of a detergent to water decreases the surface tension of the water by disrupting the hydrogen bonding between water molecules, allowing it to spread out more easily and interact with other substances.
True. When the temperature of a gas increases, the average kinetic energy of the gas particles also increases. This causes the gas particles to move faster and collide more frequently with the walls of the container, leading to an increase in the volume of the gas.
Now there's an interesting question. In general, electronegativity increases as one progresses down a period, while electronegativity decreases as one moves down the group. The most electronegative element is fluorine, while the least electronegative nonradioactive element is francium.
as the temperature increases, the rate of evaporation increases
No. In gases, 'Absolute temperature' is proportionally related to the kinetic energy of the particles. Therefore, increase in temperature results in increase in the kinetic energy of the particles.
Kinetic energy is directly related to temperature, because temperature is the average kinetic energy of an object. Therefore, as the temperature of an object decreases, its kinetic energy decreases, as well.
In the troposphere, as air temperature increases, air pressure generally decreases. This is because warmer air is less dense and exerts less pressure on its surroundings compared to cooler air.
False. Pressure decreases from the center to the outside.
False. The frequency of a wave and its wavelength are inversely proportional - as the wavelength decreases, the frequency increases, and vice versa.
False
false
False. As the amount of alcohol in a person's body increases, their driving ability decreases. Alcohol impairs judgement, coordination, and reaction time, making it dangerous to drive under the influence.
false, the temperature increases with depth
False it increases them!!!!
False. When temperature increases, the average kinetic energy of the particles also increases. This is because higher temperature means that the particles are moving faster and with more energy.
