How the temperature rises and falls?
because of the latitudinal location distance , because of being far away from the seas.
Do regular and dry ice melt in the same way?
Regular ice is frozen, solid water. When s temperature rises, it turns to water: a liquid. Dry is solid carbon dioxide. When its temperature rises, it becomes a gas instead of first turning to a liquid.
What would best show how the average daily temperature rises and falls over the course of a month?
a line graph - apex
How many phases of matter are present at the melting temperature of water?
At the melting temperature of water, there are two phases of matter present: solid and liquid. As the temperature rises above the melting point (0 degrees Celsius), the solid ice melts into liquid water.
What happens to gas when you add pressure?
Gas molecules are spread out. When they are placed under pressure they condense into a liquid.
What happens when liquid in a thermometer undergoes thermal expansion?
The liquid rises, indicating a temperature.
What happens when the temperature rises in a river and falls?
get colder
Why do refrigerants trun from liquid to gas?
This is because as the liquid passes through the refrigerator, it absorbs the heat from the food in the fridge. Therefore as heat is transferred from the food to the refrigerant, the following happen: - The temperature of the food falls - the temperature of the refrigerant rises. Thus, a higher temperature would change the refrigerant from liquid to gas.
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
A liquid in glass thermometer is sensitive to small changes in temperature due to the thermal expansion of the liquid contained inside the glass tube. As the temperature increases, the liquid expands, causing it to rise up the calibrated scale of the thermometer. Conversely, as the temperature decreases, the liquid contracts, causing it to subside on the scale. This expansion and contraction of the liquid is highly responsive to even slight temperature variations, making it sensitive to small changes in temperature.
How does a thermometer measure temeperature?
Mercury (the red liquid) is used in many older thermometers because it is the only metal which is liquid at room temperature and expands uniformly as the temperature increase. Thus, as the temperature rises and falls the mercury rises and falls inside of the thermometer and gives us a reading as to what temperature it is. Most electronic thermometers used are called thermo-resistors. These types of thermometers use semiconductors that act as temperature sensitive resistors. The colder it is, the less conductive the semiconductor is. A computer measures the conductivity of the metal and determines the temperature based on the resistance of the semiconductor.
What is the effect when heat is added to a liquid?
Temperature rises, liquid starts boiling becoming vapor
How does resistance of metal vary with temperature?
The resistance of metals rises with increasing temperature. The resistance semiconducting materials falls with increasing temperature.
What happens when the temperature in a river rises and what happens when it falls?
it gets warmer then it gets colder
What density difference is there with liquid chlorine at different temperatures?
density difference is decreasing when the temperature rises with liquid chlorine.
Is it true or false that frozen water melts?
It is a true statement that frozen water melts. As ice or frozen water rises in temperature, it will slowly change into a liquid state. It would be false to say otherwise.
What effect does temperature have on the solubility of a solid solute in a liquid solvent?
solubility increase as the temperature rises rises thus its directly proportional under normal circumstances
What happens to the saturation temperature of the liquid refrigerant inside a refrigerant tank during system charging?
multiple choice: A: It rises B: It falls C: It remains constant D: It rises slightly, then remains constant. The answer is B The Vapor leaving the refrigerant tank is replaced by the liquid that boils off into vapor as the vapor being charged leaves the tank. The liquid saturation temperature drops as liquid boils to vapor. Example; The frost on a propane tank when you BBQ or use alot of propane for ???.
