Why does liquid rise in a thermometer group of answer choices?
A thermometer has a glass tube sealed at both ends and is partly filled with a liquid like mercury or alcohol. As the temperature around the thermometer’s bulb heats up, the liquid rises in the glass tube. When it is hot, the liquid inside the thermometer will expand and rise in the tube.
What two liquids are commonly used to make a thermometer?
Thermometer liquids are mercury and alcohol.
When heated the alcohol inside a thermometer group of answer choices?
The liquid in the thermometer goes up when the thermometer is heated because heating makes the alcohol molecules of the liquid move faster. The extra speed of the molecules competes with their attraction for one another and causes them to move slightly further apart.
What is the greenest way to heat your home?
5 Green ways to heat your home
- Ground source heat pumps. Ground source heat pumps, also known as GSHPs, use pipes that are buried underground to extract heat from the ground.
- Air source heat pumps.
- Biomass Boilers.
- Solar panels.
- The RHI initiative.
- Not ready to switch to a renewable source?
What heat is most efficient?
Geothermal systems
What is the cheapest form of central heating?
What are the advantages of gas central heating?
- Gas is by far the cheapest option, at 4.17 p per kWh (kWh is the unit used to measure energy).
- Modern condensing boilers are very efficient – meaning up to 90% of the energy is used.
- Piped straight into your home, this energy source is super-reliable, and needs no storage.
What is the cheapest type of heating?
Natural gas: $1,024 Of the four main fuels used to heat US homes, natural gas is the most popular and now the cheapest, as well.
What is the cheapest heating system to install?
The electric furnace is the second to cheapest option at $3,040 while the electric boiler is the cheapest option at $2,500. Though the gas boiler is most expensive to buy at $3,500, the heat pump has the highest installation cost of $4,000, which nudged it to the top of the pile in terms of overall initial cost.
What is the most economical way to heat a house?
Active solar heating may be the most efficient option for heating your home. Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be expensive to exte…

Is it cheaper to heat your house with gas or electric?
Electricity is more expensive per unit than natural gas, making the lifetime cost higher than gas heating. Electric heating takes more time. The heat from your furnace won’t reach the high temperatures of a gas furnace. This means you’ll be a little colder for a little longer.
How cold is too cold for inside house?
The World Health Organization (WHO) recommends indoor temperatures of at least 64°F (you can drop that down to 62°F at night if you’re really looking to save on your heating bill). But if you have infants, sick or elderly people in your household, then it’s recommended that you keep the thermostat set at 70°F.
Which central heating system is best?
A gas fuelled central heating system will more than likely be cheaper in the long run. Electric boilers are 100% efficient whereas a good modern gas boiler will see about 95% efficiency.
What is the best heating system for a new build?
Gas is one of the most affordable forms of heating. What’s more, it requires no effort to use, and is ideal for producing the higher temperatures needed for domestic hot water. Modern boilers work fine with both radiant and underfloor heat distribution, as well as warm air distribution systems.
