How does temperature affect the speed of movement of particles?
Temperature affects the speed of movement of particles by increasing their kinetic energy. As temperature rises, particles move faster and collide more frequently, leading to an increase in their overall speed.
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.
How does the refractive index of a material change with temperature?
The refractive index of a material typically increases with temperature. This is because as temperature rises, the atoms and molecules in the material vibrate more vigorously, causing the density of the material to decrease and the speed of light to slow down, leading to a higher refractive index.
Why temperature affect the refractive index?
Temperature affects the refractive index of a material because it changes the speed of light passing through the material. As temperature increases, the atoms or molecules in the material vibrate more rapidly, causing the speed of light to change. This change in speed leads to a change in the refractive index of the material.
What is the equation for calculating the energy transferred when a substance is heated and its temperature rises?
The equation for calculating the energy transferred when a substance is heated and its temperature rises is Q = mcΔT, where Q is the energy transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
Does the rate of chemical reactions slow as the temperature rises?
No. The speed of all chemical rections increases when temperature rises.
Hot air rises because of a change in its?
temperature
What increases as the temperature of a soild obejct rises?
The speed of the movement of its particles increases.
When the temperature rises how does the number and size of the bubbles change?
sfgytd
How can you change the speed of a reaction?
Temperature can change the speed of some reactions.
How does temperature affect the speed of movement of particles?
Temperature affects the speed of movement of particles by increasing their kinetic energy. As temperature rises, particles move faster and collide more frequently, leading to an increase in their overall speed.
Does molecular speed change as much as the temperature?
It changes in proportion to the temperature change.
How will the speed of sound wave change if the temperature of the medium rises?
The speed will typically increase. It is hard to make a blanket statement though, because so much depends upon the type of medium being acted upon.
The speed of the particles in a substance change when what changes?
electrons
Does the speed of sound in water change with a temperature change?
yes it is changing. It's increasing with the temperature.
What is Heat flows into an object an its temperature rises an the change in temperature?
Caused by vibrations of the atoms or molecules that make up the object.
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.
