If a certain star has a peak wavelength of 700NM then its surface temperature is about?
Approximately 4200K. This is based on Wien's displacement law, which relates the peak wavelength of a black body radiator to its temperature.
How does uneven heating of the earth cause ocean currents?
Uneven heating of the Earth's surface by the sun leads to temperature differences in the atmosphere and ocean. This temperature variance creates areas of high and low pressure, which in turn drive wind patterns. Wind patterns then influence the movement of surface ocean waters, creating ocean currents.
Are Global winds created by unequal heating of Earth's surface?
Yes, global winds are created by the unequal heating of Earth's surface. As the Sun heats the Earth, different areas heat up at different rates, creating variations in air temperature and pressure. This temperature and pressure gradient drives the movement of air masses, resulting in the formation of global wind patterns.
The pressure differences that make wind happen are caused?
by the uneven heating of the Earth's surface, which creates variations in air temperature and pressure. As warm air rises and cool air sinks, it sets up convection currents that result in the movement of air masses, known as wind.
How does surface area affect temperature?
Surface area does not really affect temperature. It affects heat transfer. A car's radiator has thousands of fins that increase the surface area to increase heat transfer between the air and water. The radiator is a heat exchanger that follows the rules found here Based on heat transfer, surface area can indirectly affect temperature. If your house is surrounded by a paved road the temperature will not be as warm as if it were located in the center of a huge parking lot. The larger parking lot area can convert more radiant energy from the sun and release more to the air surrounding your house.
What is uniformity of heating in reheating furnace?
surface to core temperature islow
What advantage does a double radiator have over a single radiator?
A double radiator provides more surface area for heat exchange compared to a single radiator, allowing for more efficient cooling or heating of a room. This can result in faster temperature regulation and potentially lower energy costs.
What is Device with a large surface area that warms the surrounding air by conduction?
A radiator is a device with a large surface area that warms the surrounding air by conduction. It transfers heat from a hot surface to the air through direct contact, heating the room efficiently.
Local winds can be caused by heating of the Earth's surface?
Yes, local winds are caused by the unequal heating of Earth's surface, which creates variations in air pressure and temperature. This temperature difference leads to the movement of air from areas of high pressure to areas of low pressure, generating local wind patterns.
Explain how the uneven heating of Earth's surface creates different temperature zones.?

What are the benefits of using geothermal heating?
Yes, it's becoming a popular method because it's considered to be a green technology. They are a proven energy saving technology because they take advantage of the relativly constant temperatures found a few feet below the earth's surface.
Describe the relationship between the angle of insolation and the rate of heating a surface.?
The angle of insolation into a surface is largest when the surface directly faces the Sun. That coincides with the temperature rising. So the angle of insolation goes up as the temperature goes up.
What are Characteristics of global warming?
A rise in temperature of both the atmosphere and the surface of the earth. Global means all over the world; warming means heating up, rising in temperature.
If a certain star has a peak wavelength of 700NM then its surface temperature is about?
Approximately 4200K. This is based on Wien's displacement law, which relates the peak wavelength of a black body radiator to its temperature.
The unequal heating of the earths surface is?
The unequal heating of the Earth's surface is caused by factors such as the angle of incidence of sunlight, atmospheric circulation patterns, and the distribution of land and water. This leads to variations in temperature and weather patterns across different regions of the planet.
Is a radiator a thermal energy store?
A radiator in a central heating system works by convection mainly, that is air currents are set up which carry the heat around the room. Radiation also works to some extent, but is not the main way the heat is transferred, because the surface temperature of the radiator is limited to about 50degC for safety reasons. A hot radiator clearly stores some energy, the steel of the unit plus the hot water inside it, but if you shut off the water flow it will soon cool down. Radiators are designed for continuous heating, not storage.
What will be 5 examples of thermal energy in the real world?
Boiling water on a stove: The heat source applies thermal energy to the water molecules, causing them to increase in temperature and eventually boil. Sunlight warming the Earth's surface: Solar radiation contains thermal energy that is absorbed by the Earth's surface, leading to an increase in temperature. Heating a room with a radiator: The radiator emits thermal energy in the form of heat, warming the air in the room. Campfire: The burning wood releases thermal energy in the form of heat and light. Human body: Our bodies generate and maintain thermal energy through metabolic processes to regulate internal temperature.
