Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
When heat flows out of an object and its temperature decreases the change in temperature is?
The change in temperature is a decrease. Heat flowing out of an object causes its particles to lose kinetic energy, resulting in a decrease in temperature.
What is the effect of a decrease in volume of a sealed container of gas with no change in temperature?
A decrease in volume of a sealed container of gas with no change in temperature leads to an increase in pressure according to Boyle's Law. This is because the gas molecules are confined to a smaller space, resulting in more frequent collisions with the container walls.
When evaporation happens does the temperature increase or decrease?
When evaporation happens, the temperature decreases. This is because the energy required for the phase change from liquid to gas is absorbed from the surroundings, leading to a cooling effect.
What is the change in temperature from 25 degrees c to -10 c?
The change in temperature from 25°C to -10°C is a decrease of 35°C.
Ice melting is an example of a?
Retreat,Or a decrease in temperature.
What are the two physical properties that change with temperature?
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
Would something turning hot to cold be a chemical change?
A decrease in temperature is a physical change, not chemical.
When you put a balloon filled with air into a refrigerator and it get smaller is that a physical change or a chemical change?
That is a physical change. The decrease in size of the balloon when placed in the refrigerator is due to the decrease in temperature, causing the air molecules to contract and take up less space. No new substances are formed, so it is not a chemical change.
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
Is hot and cold a physical change?
Temperature is a physical phenomenon Change of temperature is a physical change.
What would this physical change most likely indicate about changes in the status of the pond?
A decrease in temperature has moved the algae into the stream.
When melted butter soldifies in the refrigerator is that physical or chemical change?
When melted butter solidifies in the refrigerator, it is a physical change. The butter is simply changing from a liquid state to a solid state due to the decrease in temperature, with no change in its chemical composition.
Is a hot glass cracking when placed in cold water a physical change?
it is a physical change because the state of the glass does not change.it cracks because of the rapid change of temperature
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
Is diluting A physical or chemical change?
Diluting a substance is a physical change because it does not alter the chemical composition of the substance. It simply involves mixing the substance with another (usually a solvent) to decrease its concentration.
