Blood pressure is the force exerted by the blood against the inner walls of the blood vessels
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.
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.
The statement is false. Faster-moving gas particles have greater kinetic energy, which corresponds to a higher temperature. In thermodynamics, temperature is a measure of the average kinetic energy of particles in a substance; therefore, as particle speed increases, so does the temperature.
False. There is a limit to the rate of photosynthesis even as light intensity increases. Once the saturation point is reached, the rate of photosynthesis remains constant.
Blood pressure is the force exerted by the blood against the inner walls of the blood vessels
False
as the temperature increases, the rate of evaporation increases
false
false, the temperature increases with depth
False
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.
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.
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.
False. The temperature increases from the surface of the Earth towards its center. This is due to the heat generated from the Earth's core and the radioactive decay of elements in the Earth's mantle and crust.
It is false that an ice cube melts when it's mechanical energy increases.
False.
