The lower the specific heat the faster the temperaature will change.
You can learn it from the formula:
Q = m * Cs * ΔT
You can solve for ΔT
ΔT = Q / ( m * Cs)
Given the heat (Q) and m (100 g) are equal for the five samples:
ΔT = [Q / m] / Cs. = constat / Cs
So you see the inverse relation between the change of temperatura and the specific heat.
So, the order of change of temperature is given by the specific heat: the lower the specific heat the faster the change of temperature.
With that analysis you can calculate the order in which the cubes will reach the target temperature.
The combustion of any hydrocarbon yields water and carbon dioxide. We will now construct a balanced equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Each mole of propane requires 5 moles of oxygen.
Answer:
Because milk has higher KE than ice, KE is transferred from the milk to the molecules of ice.
Explanation:
The best statement that expresses the transfer of kinetic energy(K.E) is that kinetic energy is transferred from the milk to the ice.
Kinetic energy is form of energy due to motion of the particles of a medium. In this regard, we are dealing with heat energy.
- Heat energy is dissipated from a body at higher temperature to one at a lower temperature.
- Ice is at a lower temperature which is 0°C
- Heat will be transferred in form of thermal energy from the body at higher temperature to one with a lower temperature.
- This is from the milk to the molecules of ice.
