Because of the weather when it become hotter & hotter day-by day ,also change in on the ozone layer can cause the resistant.
Tungsten is a naturally occurring metal element, known for its high melting point and strength. It is primarily composed of pure tungsten, with small amounts of other elements such as carbon and oxygen.
Your apartment gets hotter at night because during the day, the sun warms up the building and the heat gets trapped inside. Without sunlight to counteract this effect at night, the heat remains inside, causing the temperature to rise.
The temperature increases as you get closer to the center of the Earth. This is due to the heat generated by the radioactive decay of elements in the Earth's core and the compression of materials under the immense pressure at the center, reaching temperatures of over 5,700 degrees Celsius at the inner core.
An increase in temperature can lead to the expansion of materials, a change in state (for example, from solid to liquid), an increase in the speed of chemical reactions, and can also cause biological processes to speed up or slow down.
When air gets hotter, its particles move faster and spread out, causing the air to expand and become less dense. Conversely, when air cools down, its particles slow down and move closer together, causing the air to contract and become denser.
When heat is supplied to tungsten or for that matter any metal its molecules start vibrating more vigorously and thus collide with each other thus opposing the flow of electrons to a greater extent and so resistance is increased
the therminster will get hotter when the resistance is lowed
The electrical resistance of a light bulb increases when it is turned on As a resistor, the tungsten light bulb has a positive resistance coefficient. This means that the electrical resistance goes up when the filament becomes hot. For example, a 100 watt light bulb operated at 120 volts - it does not matter if it is AC or DC for this calculation - will have a resistance of 144 ohms when hot and draw .833 ampere. When cold the filament typically has a resistance of only 10 ohms which increases as the filament heats up.
The deeper into the Earth you go it gets hotter and hotter.
It gets hotter
Each time the weather get hotter the ladybird gets lighter
which gets hotter land or water
When air gets hotter, or when any gas gets hotter, it expands. This means its density will decrease; therefore, cooler (and heavier) air will push it up.When air gets hotter, or when any gas gets hotter, it expands.

When the current increases as a voltage is applied to the bulb it causes the bulb's special wire filament to get so hot that it glows very brightly. The heating causes changes in the normal electron lattice of the filament, creating more barriers to the flow of the electrons and therefore the resistance of the wire increases as it gets hotter.
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
Because it is colder in the winter so you wear hotter and bigger , and jackets , clothes but when it gets hotter in the summer you can just wear shorts and t-shirts
