Is the R-value of insulation indicate resistance to heat flow?
yes the R-value does indicate resistance to heat flow
What is a specific heat of glass?
The average value should be about 0.438
How does loft insulation save heat energy?
Heat always flows from a warm region to a cooler region. An uninsulated house loses heat at a faster rate during cold climates than an insulated one. Insulating a loft reduces the amount of heat loss from the roof by means of installing insulating materials such as fiberglass matting, which reduce the U-value of the loft. The U-value provides an indication of how much heat loss occurs from an area, the higher the U-value, the greater the heat loss.
What is R factor in heat insulation?
An R-value is a unit of thermal resistance for a particular material or assembly of materials (such as an insulation panel). The R-value depends on a solid material's resistance to conductive heat transfer.
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
Heat engine utilizes low heat value of fuel or high heat value of fuel?
Heat engine utilizes low heat value of oil and also the fuel oil consumption for IC engine usually based on high heat value of oilby Shyam
When heat flows into a system its value is positive. When heat flows of a system its value is negative.?
when heat flows Out of a system
What is gross calorific value and useful heat value of coal?
what is the differnence between gross calorific value and useful heat value
When flows into a system its value is positive. When heat flows out of a system its value is negative.?
heat
What is the specific heat value for water?
The specific heat value for water is 4.18 J/goC.
Why charcoal have high value of heat combustion than petrol?
Petrol has a higher value of the heat of combustion.
When heat flow into a system it's value is when heat flows out of a system it's value is negative?
positive < Mitzy >
When what flows into a system it's value is positive when heat flows out of the system it's value is negative?
heat. apex.
When heat flows into a system its value is When heat flows out of a system its value is negative?
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.
Is the R-value of insulation indicate resistance to heat flow?
yes the R-value does indicate resistance to heat flow
The r value of insulation indicate resistance to heat flow?
yes the R-value does indicate resistance to heat flow
Why the experimental value of specific heat capacity is higher than the standars value?
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
