What else can I help you with?
Is convection a method of heat transfer?
Yes, convection is a method of heat transfer where heat is transferred through the movement of fluids (liquids or gases) due to density differences. This movement can be either natural convection, driven by temperature differences, or forced convection, caused by external sources such as fans or pumps.
What are the 3 types of heat sources?
The three types of heat sources are conduction, convection, and radiation. Conduction is heat transfer through direct contact, convection is heat transfer through the movement of fluids, and radiation is heat transfer through electromagnetic waves.
Is breathing internal of external force?
Breathing is an internal force, controlled by the diaphragm and other muscles in the respiratory system. It is a vital process that brings oxygen into the body and removes carbon dioxide, essential for sustaining life.
Does convection need a medium?
Yes, convection requires a medium such as air, water, or other fluids to transfer heat. Heat is transferred through the movement of the medium itself, either through natural convection (by differences in temperature causing fluid movement) or forced convection (by external means like a fan or pump).
Is convection a heat transfer?
Yes, convection is a heat transfer mechanism where heat is transferred through the movement of fluid (liquid or gas). This movement can be either natural convection (due to density differences) or forced convection (due to external forces like fans or pumps).
How does energy enter the Earth system from internal sources through convection and from external sources through radiation from the Sun?
Energy from internal sources enters the Earth system through convection as heat is transferred from the mantle to the surface through the movement of molten rock. External energy from the Sun enters the Earth system through radiation, with sunlight being absorbed by the Earth's surface and converting into heat energy. Both processes play a crucial role in driving the Earth's climate and geological processes.
Is convection a method of heat transfer?
Yes, convection is a method of heat transfer where heat is transferred through the movement of fluids (liquids or gases) due to density differences. This movement can be either natural convection, driven by temperature differences, or forced convection, caused by external sources such as fans or pumps.
Do corporations rely more on external or internal funds as sources of financing?
Sixty percent of corporations through the selling of new securities uses external funds as sources of financing whereas only forty percent of funds are raised internally.
What is the internal and external conflict in The Last Book in the Universe?
The internal and external conflict are Friends losing others and living through life with out problems
How do you Evaluate internal and external growth strategies?
You do this through a SWOT analysis.
Are sparrows external or internal fertilisation?
Sparrows exhibit internal fertilization, where the sperm fertilizes the egg inside the female's body. The male bird transfers sperm to the female through copulation.
Does a dog reproduce with internal or external fertilization?
Internal. Dogs mate through copulation and internal fertilisation, like all mammals (including humans).
Identify and explain the internal and external sources of data and information with effect to a business organisation?
1. Internal Sources:Internal sources of data are those which are obtained from the internal reports of an organization. For instance, a factory publishes its annual report on total production, total profit and loss, total sales, loans, wages to employees, bonus and other facilities to employees etc.2. External Sources:External sources refer to the information collected] outside agencies. It can be collected from primary as well as secondary sources; type of information can be collected through census or sample method by conduct! Surveys and investigation.For instance, to study the problem of transportation in Orissa, if we obtain the information from Orissa Road Transport Corporation, it would be known as external sources of data.

What is external diameter?
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
