Explanation: coarse adjustment
Answer:
Q = 8.68 × 10⁴ J
Explanation:
We can calculate the heat required to melt a mass of ice, that is, to change it from the solid phase to the liquid phase, at a constant temperature of 0 °C, using the following expression.
Q = ΔH°f × m
where,
- ΔH°f is the standard enthalpy of fusion (ΔH°f for water: 334 J/g)
Q = ΔH°f × m
Q = 334 J/g × 260 g
Q = 8.68 × 10⁴ J
Answer:
Atomic number
Explanation:
Because atomic number is unique for each element and never changes
Refrigerants will decompose when exposed to high temperatures from flames or electric resistance heaters. Decomposition may produce toxic and irritating compounds, such as hydrogen chloride and hydrogen fluoride
