Why does a metal spoon feel colder than a wooden spoon?
Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. It is because the metal conducted heat faster that it feels colder than the wood, which conducted heat slower.
Why is the door knob colder than the door?
The answer lies in the heat transfer between one’s hand and the object. Metals are good heat conductors, better than wood. Thus, heat gets transferred very fast from one’s hand to the door knobs, making one’s hand instantly lose lots of heat, and hence instantly feel cold.
Can heat flow between two objects?
Is it possible for heat to flow between two objects with the same internal energy? Heat will flow naturally from the object with the higher temperature to the object with the lower temperature. The object with the high temperature may or may not be the object with the higher internal energy.
What does the C represent in the heat formula Q MC ∆ T?
The quantitative relationship between heat transfer and temperature change contains all three factors: Q=mcΔT Q = mc Δ T , The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
Which object has the higher temperature after being left outside for an entire dark winter night a metal door knob or a Styrofoam pad?
1 answer below » Which object has the higher temperature after being left outside for an entire dark winter night: a metal door knob or a styrofoam pad? 1)The metal door knob has the higher temperature.
Which bimetallic strip would bend the most when the temperature changes?
Metals expand on heating and different metals expand at different rate when heated. Brass and Iron together form the bimetallic strip. The rate of expansion and contraction of brass is more when compared to Iron, that is, brass expands more than Iron when heated and contracts faster than iron when cooled.
Why are door knobs and vehicle handles cooler compared to the surrounding temperature in winter?
During winter, the door and handle’s temperature is the body temperature. Therefore, heat flows horn the body into the object touched. Since, metallic handle being a good conductor takes more heat from the finger touching it, we feel cold. Wooden door being a poor conductor takes less body heat and appears less cold.
