What else can I help you with?
What is a large section of the lower troposphere with uniform temperature and humidity called?
air mass
What is the lower opening of the digestive tract?
The lower opening of the digestive tract is called the anus. It is where waste material from the body is expelled during the process of defecation.
What combination of factors is most suitable for increasing the electrical conductivity of metals?
Resistivity is a constant for any particular material, and independent of that material's physical dimensions or shape. However, it does vary with temperature which is why resistivity is always quoted at a particular temperature. Variations in resistivity due to temperature change is the reason that the resistance of a material varies with temperature. In SI, resistivity is expressed in ohm metres.
What is the relationship between specific heat and rate of heating?
change in temperature does not effect specific heat. for example,specific heat of water is 4.14 j/g.k at any temperature
Do you turn temperature up or down for cool air?
To cool the air, you typically want to turn the temperature down by setting the thermostat to a lower temperature. This tells the air conditioning system to come on and remove heat from the air, creating a cooler indoor environment.
How is evaporation reduced?
Sealed environment. Lower temperature.
What is the thermal energy that flows from a material with a higher temperature to one with a lower temperature?
Heat is the thermal energy that flows from a material with a higher temperature to one with a lower temperature. This flow of heat occurs due to the temperature difference between the two materials, with heat transferring in the direction of decreasing temperature.
Which way does thermal energy travel?
Thermal energy travels from a higher temperature to a lower temperature. This process occurs through conduction, convection, or radiation, depending on the material and environment involved.
What happens to the temperature intensity of material between points D and A?
The temperature intensity of the material decreases between points D and A. This is because heat is transferring from the higher temperature point (D) to the lower temperature point (A) through the material, causing it to cool down.
Does lava get hotter or colder?
Lava (and any other material) will cool down if it is surronded by material that is at a lower temperature than itself and heat up if the surrounding material is hotter. By definition, lava is molten rock that has been erupted onto the earth's surface. As such it is surrounded by material that is at a much lower temperature than itself so will lose heat and so decrease in temperature.
What temperature causes solids to liquify?
The melting temperature for solids depends on the material of the solid. For example, ice melts at a much lower temperature than iron.
Why critical temperature is lower than melting temperature?
the critical temperature is for the phase stability? When the phase changes,the energy needed is smaller than the material melton,
What is the process of passing heat from one material to anther?
The process of passing heat from one material to another is called heat transfer. This can occur through conduction (direct contact between materials), convection (movement of fluids), or radiation (emission and absorption of electromagnetic waves). Heat always flows from a higher temperature material to a lower temperature material until equilibrium is reached.
What are the two condition necessary for the conduction of heat?
The two necessary conditions for the conduction of heat are a temperature gradient (difference in temperature) and a material that can conduct heat, such as metals or solids. Heat energy flows from areas of higher temperature to areas of lower temperature through the material.
Why did the temperature recorded by lower thermometer continue to rise dramatically after the heating ceased?
The lower thermometer continued to rise dramatically after the heating ceased due to a phenomenon called thermal lag or hysteresis. This occurs because the lower thermometer takes time to adjust to the changes in temperature in its environment. Additionally, heat may still be transferring from the heated area to the lower thermometer even after the heat source is removed.
What is heat transfered through a metal spoon called?
Heat transfer through a metal spoon is called conduction. This occurs as heat travels through the metal by the collision of particles within the material. The metal spoon acts as a conductor, allowing the heat to move from a higher temperature area to a lower temperature area.
What is the transfer of thermal energy from an object of higher temperature to an object of lower temperature?
The increase in the kinetic energy of a material's particles from an object of higher temperature to one of lower temperature is known as heat transference.heat
