Because it takes time for the pressure to build enough to push the lava out.
Answer:
100 degrees, -41 degrees Celcius, and -24 celcius
Explanation:
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:
Điều này là kết quả của quá trình hydrat hóa các ion: lực hút của các phân tử nước đối với Công thức phản ứng của kali hydroxit với các ion nước. Phản ứng có thể được viết dưới dạng KOH (s) → K⁺ (aq) + OH⁻ (aq).
Explanation:
Answer:
The object will not be in motion
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. ... Objects resist changes in their velocity.
