Question
What is the physical state of water at 250⁰
C?Solution
Water occurs in solid as well as liquid state at 0°C temperature. The physical state of water at 250°C is the gaseous state because it reaches above the boiling point of water, 100°C. At 25°C, the physical state of water remains a liquid. In the gas phase, the molecular forces are very weak. Air, Natural gas, Carbon dioxide are examples of gases.
5.5 × 3.2 × 2.3 = ?
33 × ?2 – 6 × 5 = 3270
∛857375 + ∛91125 = ? + √6889
- Find the simplified value of the given expression:
9 of 6 ÷ 3 × 6² + √64 – 15 35% of 840 + 162 = ? – 25% × 300
(11/12) × (18/22) × (4/3) + 3 = ?2
The value of 43-3× (4×6+12/3 ×6-4×5) +4?
