Is cold metal a better conductor of electricity than warm metal?
In hot metals the kinetic energy of electrons becomes higher and they move randomly so their movement in one direction becomes decreased so the conductance becomes decreased.
What is delta t in refrigeration?
In refrigeration, delta t (ΔT) refers to the temperature difference between two points, typically the evaporator and condenser temperatures. It is an important factor in determining the efficiency and performance of a refrigeration system, with a larger delta t generally indicating better heat transfer and system effectiveness.
Which is better mercury or alcohol thermometers for low temperature measurements?
Alcohol thermometers are generally better for low temperature measurements as they have a wider temperature range, reaching lower temperatures than mercury thermometers. Additionally, alcohol is less toxic than mercury, making it safer to use in certain applications.
Why you use nitrogen gas in the tire?
Nitrogen gas is used in tires because it has larger molecules compared to oxygen and other gases, reducing the rate at which it permeates through the tire rubber. This helps to maintain tire pressure for longer periods, leading to better fuel efficiency, longer tire life, and improved safety.
What are the advantages of pewter casting at a low temperature?
Casting pewter at a low temperature can help reduce the risk of porosity in the final piece, leading to better surface finish and detail retention. It also minimizes the risk of thermal shock to the mold, prolonging its lifespan. Additionally, low-temperature casting can be safer for the caster as it reduces the risk of burns or other injuries associated with high-temperature metals.
Is a gram or kilogram better for measuring the weight of a dog?
kilogram is about 2.2 pounds, so a kilogram is better
Which would be better to keep you warm through the cold night a 10 kilogram iron brick or a 10 kilogram jug of hot water at the same temperature?
The water will keep you warmer than the brick. The water has a higher heat volume and will take longer to cool down than the brick.
What is the better estimate for the mass of a textbook 1 gram or 1 kilogram?
1 kilogram, one gram would be about a piece of paper
Which is better value for money- 2 kilogram of grapes for 3.40 or 1 kilogram for 1.80?
The answer is 1kg for $1.80. <3
Which metric unit of mass would better measure a necktie a milligram or a kilogram?
Neither of those units will produce a very convenient number. But of the two, the kilogram is the better choice.
Which is better value for money- 4.5 kilogram of bananas for 5 or 3.0 kilogram for 3?
4.5 kg for 5 b
How does the temperature of water affect the time it takes to freeze an ice cube?
Mass holds temperature--the more mass, the better it holds temperature...but, conversely, the longer it takes to get it to temperature all the way through.
What is the better buy 1 kilogram of cat food for 2.75 or 12.5 kilogram for 38.15?
1 kg for $2.75 is better you pay 3.05 per kg for the 12.5 kg bag
Who is better kilogram or Kobe?
obviously kobe. kg is wayyy to old
Which is better value for money-2 kilogram of grapes for 3.40 or 1 kilogram for 1.80?
teah knows best : 1 kg for $1.80 :)
How many bound in kilogram?
If you means pounds, then there are 2.2 pounds in a kilogram
What is the relationship between temperature and air conductivity?
The relationship between temperature and air conductivity is that as temperature increases, air conductivity also increases. This means that higher temperatures can lead to better conductivity of electricity through the air.
