Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
In is convection the main type of heat transfer?
Whether convection is the main type of heat transfer or not depends on the specific situation.
What is the difference between a fluid and a liquid?
Fluids versus liquidsAll liquids are fluids but not all fluids are liquids. The scientist (or engineer) will make that distinction but the non-scientist frequently doesn't. Fluids flow. They include liquids and gases. Liquids are a type of fluid that flows and takes the shape of its container but does not expand to fill its container. (Gases do that.) Liquid is the second state of matter, between solid and gas.Liquids do not expand, gases do. The main point is that gases and liquids are both fluids.both liquids and gases are called fluids
How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
How does thermal energy move in liguids and gases?
Thermal energy, also called heat, moves through liquids and gases in three ways: 1. Conduction (which can also occur in solids). Conduction is when heat directly travels through matter. As hot molecules move back and forth, they bump into cooler molecules, and transfer some of their heat energy to those molecules. 2. Convection (which can only happen in gases and liquids). Convection is when hot fluids (a fluid is a gas or liquid) expand, and thus are less dense. The hotter fluids float to the top, and the denser, cooler fluid sinks. As they come in contact with each other, the hot fluid transfers heat energy to the cooler fluid. In these scenarios, the main heat source is usually at the bottom. Thus, the cooler fluid that sank gets hot and floats back up, while the fluid on the top cools off and sinks. This cycle creates something called a convection current. 3. Radiation (which doesn't require any matter). Radiation is heat that travels in the form of infrared waves. One example of this is that heat energy comes from the sun, and that is what keeps Earth warm (note that the radiation does have to pass through the atmosphere; so heat can travel as radiation through a fluid).
By which mode of heat transfer heat is transferred in solids?
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..

What are the main fetures of a respirotory surface?
To be permeable to gases & impermeable to liquids. To be as large as possible.
How fast do things spread out in liquids compared to gases?
Gases spread out faster than liquids, and liquids spread out faster than solids. Gases, liquids, and solids are the three main phases of matter. A material moves to a different phase if its kinetic energy is changed enough (Kinetic energy is a measure of heat or temperature). For example, if you heat an ice cube (solid water), it will melt into water (liquid water). Gases have the highest kinetic energy. The molecules inside a gas are the fastest moving of the three phases. That means gas will spread out the fastest. Kinetic energy: Gas ---> Liquid ---> Solid [Decreasing] Solid ---> Liquid ---> Gas [Increasing]

How is heat prevented from transferring?
The main way of heat transfer is conduction. Mostly in the cases of solids , so by preventing contact , heat transfer can be hampered.
What method of heat transfer plays the primary role in the formation of an air mass?
Convection is the main heat transfer in the troposphere.
What is the main way heat is transfer in the troposphere?
Convection Currents
What is the main purpose of the cooling system?
Transfer heat energy.
What is the main purpose of a cooling system?
Transfer heat energy.
Are there any other types of heat transfer?
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
