Why is a clothes dryer an example of thermal energy?
Perhaps because it uses heat to dry the clothes.
What is difference between dry heat and moist heat?
Dry heat is the absolute substance temperature without accounting for the modulating effects of water vapor in the substance. Moist heat is the relative substance temperature when accounting for the modulating effects of water vapor.
Why is a rag a better conductor of heat when wet than when dry?
A dry rag has quite a bit of air trapped in its structure, and air is an insulator of heat. Replace the air with water, which conducts heat much better than air does, and the heat conductivity will be greatly increased.
What type of energy causes cement to dry?
concrete
At what temperature is the absence of heat?
Absance is spelled absence. Heat is a noun used to describe the higher temperature applied or in relation to another something. It isn't really ever absent... FOR EXAMPLE: 32F could be hot compared to dry ice.
What are the application and relative advantages and disadvantages of dry heat and moist heat sterilization?
Advantages: 1. It is faster method of sterilization then dry heat method. 2. Additional parameter "pressure" is involved 3. We can easily sterilize the media solution. 4. It faster method of sterilization. Disadvantages: 1. Glass ware might get broken down. 2. Mishandling may lead to serious accident or explosion.
Is autoclave example of dry heat sterlization?
no.it is an example of moist heat sterilisation
What method did earliest people use to cook food?
what method did earliest people use to cook food first? dry heat or moist heat
What is a dry-heat method that uses a rack and open pan?
Convection.
What are the disadvantages of using the new carbon dioxide dry cleaning?

What is the advantages and disadvantages of dry friction?

Why is a clothes dryer an example of thermal energy?
Perhaps because it uses heat to dry the clothes.
Compare the effectiveness of autoclaving and dry heat method?
Steam sterilization uses much less energy and time than dry heat methods. In order to kill spores a dry heat sterilizer needs to reach and maintain 170°C for one hour. An autoclave only needs to reach 121°C for 15 minutes.
If a person wants to make a room free from microbes and their spores what sterilization method would you advice him to use?
dry heat sterilization
What is formula for boiler efficiency?
boiler efficiency calculation methods:Input-output methodη = Output / Input Output is defined as the heat that is absorbed by working fluid. Input is defined as the chemical heat of fuel plus the heat that is added to working fluid, air, gas and other fluid circuit in which the fluid circuit across thin layer.Heat Loss MethodHeat loss method is the method that is used to calculate the percentage amount of heat which is not useful. This method is very effective used in an attempt to find potential savings of boiler with heat balance. There are several factors act as the source of heat loss combustion. These factors will be used to calculate boiler efficiency based on heat loss method. The source of heat loss can be seen as following below:a. Heat loss due to dry flue gasHeat loss due to dry flue gas is the heat loss which is contained in dry flue gas such as CO2, O2 and N2. These gases are one of causes of heat loss in combustion process. The high temperature of flue gas coming out from boiler affect amount of heat loss.The weight and heat loss of dry flue gas of combustion of coal can be calculated as following formula:Wdfg = mCO2 + mSO2 + mO2 + mN2Eloss dfg = Wdfg x Cp x (To - Ts)Where:Wdfg = weight of dry flue gas (kg/kg coal)Eloss dfg = heat loss in dry flue gas (kJ/kg)To = temperature of dry flue gas coming out from boilerTs = temperature of surroundingby Gajanan Nalegaonkar
Which is hotter moist heat or dry heat?
Conductivity. Moisture conducts the heat better than a dry system.
What is the example of Dry heat sterilization?
we have 4 types for dry heat steralization 1.red heat eg. heating of platinum loop,points of forceps 2.flaming eg. used for needles,mouth of culture tubes 3.hot air oven temp. of 160 c fpr 1 hr is employed and its the best method for stterelization dry glasswares,forceps,scalpels,powders,fat oils, greases. 4.infra red radiation the source employed is an electrically heat element a temp. of 180 c can be attained
