which factors are needed to determine the amount of heat absorbed by an aluminum cube after it is warmed? check all that apply. final temperature of the cube initial temperature of the cube mass of the cube melting point of aluminum specific heat of aluminum volume of the cube
Answer
Explanation:
Step1: Recall heat - absorption formula
The formula for heat absorbed $Q = mc\Delta T=mc(T_f - T_i)$, where $m$ is the mass, $c$ is the specific heat capacity, $T_f$ is the final temperature and $T_i$ is the initial temperature.
Step2: Analyze each option
- Final temperature ($T_f$) is needed as it is part of the $\Delta T=T_f - T_i$ term in the heat - absorption formula.
- Initial temperature ($T_i$) is needed for the $\Delta T=T_f - T_i$ term.
- Mass ($m$) of the cube is a factor in the formula $Q = mc\Delta T$.
- Melting point of aluminum is not relevant for calculating heat absorbed during a non - melting temperature change.
- Specific heat of aluminum ($c$) is a factor in the formula $Q = mc\Delta T$.
- Volume of the cube is not directly in the heat - absorption formula. If we know the density, we can convert volume to mass, but directly volume is not needed.
Answer:
- final temperature of the cube
- initial temperature of the cube
- mass of the cube
- specific heat of aluminum
