thermostat maybe stuk open fit a new one
No. Temperature is a property of matter - just like mass or length.
how temperature can bring about changes in the state of matter
Bromine is in its liquid state of matter at room temperature.
Cold is not a matter, it is a characteristic of a matter (a low temperature).
Cold is not a matter, it is a characteristic of a matter (a low temperature).
If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.
i think it does matter
Thermometer is based on the expansion of matter as temperature increases.
Thermal energy is energy that is related to heat and the temperature of matter.
the state of matter at room temperature for the element Europium is a liquid.
Temperature is a property of matter as opposed to being matter itself. You can't go to the store and buy a bottle of temperature. "Why" is a bit of a nonsensical question ... that's just the way it is.
Temperature is a measure of the micro-kinetic energy of matter, the vibrational energy of the atoms or molecules making up the matter. The more energetic the vibration the higher the temperature.
