What is a large section of the lower troposphere with uniform temperature and humidity called?
air mass
Relation between melting temperature and sintering temperature?
The idea of sintering is heating a powder until it is hot enough to stick to itself, then reshaping it and letting it set. The temperature used is always lower than the melting point of the material.
Why is there a lower limit to temperature but not an upper limit?
lower limit because the particles have zero energy. there is no upper limit because particles can move as fast as they like. There is an upper limit on temperature, called "Planck Temperature". It is approximately 1.42e32 Kelvin! This temperature is the maximum temperature something can attain, with the physics we understand.
What is an erosional-depositional system?
It is where elevated material is transported to lower areas by wind, ice, water, and gravity, and deposited in a still environment, like a basin, lake, or ocean.
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.
How is evaporation reduced?
Sealed environment. Lower temperature.
Why does ice melt at a lower temperature with salt?
It's due to the material in the salt that allows the ice's mass to lower. The temperature doesn't effect the process in a good way. Actually, it helps the ice melt more with the salt material.
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
What is the seemingly lower temperature due to excessive breeze?
The lower temperature is called wind chill
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 movement of thermal energy from a substance at a high temperature to a substance at a lower temperature called?
Heat
Why does some substances freeze faster then others?
They may have lower freezing point, or there may be bigger temperature difference between them and the environment.
What is a large section of the lower troposphere with uniform temperature and humidity called?
air mass
Why do things get brittle when frozen?
This is due to molecular mobility, which changes with temperature. At colder temperatures, the molecules within a material may be less able to slip and slide past each other as they do at normal temperatures. At normal temperatures, the material will have a certain amount of elasticity or ductility and is able to deform under stress without a crack appearing. At lower temperatures, the elasticity or ductility is lost and when placed under stress, the material may crack and give rise to a brittle fracture. The temperature at which this change in material properties occurs is called the "glass transistion temperature" denoted as "Tg".
Thermal energy that flows from higher temperature to lower temperature is called what?
im pretty sure its heat. im not sure but that is what i remember it as.
