An air tight container having a lid with negligible mass and an area of 8 cm${}^2$ is partially evacuated. If a 48N force is required to pull the lid off the container and the atmospheric pressure is 1.0 x 10${}^5$Pa, the pressure in the container before it is opened must be:

Q. An air tight container having a lid with negligible mass and a area of $8c{m}^2$ is partially evacuated . If a 40N force is require to pull a lid off the container and the atmospheric pressure is $1.0\times {10}^{5}Ps$ ,the presure in the container before it is opened must be

Q. An airtight box, having a lid of area $80c{m}^2$, is partially evacuated (i.e., has low pressure than outside atmosphere). Atmosphere pressure is $1.01\times {10}^{5}Pa$. A force of $600N$ is required to pull the lid off the box. What was the pressure in the box?

Q. An airtight box, having a lid of area 50 cm² is partially evacuated. Atmospheric pressure is 1.01 × 10⁵ Pa. To open the lid, net outward force should be equal to net inward force. If a minimum force of 500 N is required to pull the lid off the box. The pressure in the box was

50 cm² क्षेत्रफल के ढक्कन वाले एक वायुरोधी बक्से को आंशिक रूप से निर्वातित किया जाता है। वायुमण्डलीय दाब 1.01 × 10⁵ Pa है। ढक्कन को खोलने के लिए नेट बाह्य बल, नेट आन्तरिक बल के बराबर होना चाहिए। यदि बक्से के ढक्कन को ऊपर खींचने के लिए 500 N के न्यूनतम बल की आवश्यकता होती है, तब बक्से में दाब था

Q. One mol of ${NH}_{4}Cl$ is kept in an open container and then covered with a lid. The container is now heated to $600K$ where all ${NH}_{4}Cl$ dissociated into ${NH}_3$ and $HCl$. If volume of the container is $24.63$ litres. Calculate what will be the final pressure of gases inside the container. Also find whether the lid would stay or bounce off if it can withstand pressure difference of $5.5atm$. Assume that outside air is at $300K$ and $1atm$ pressure.

Q. One mole of $N{H}_{4}Cl\left(s\right)$ is kept in an open container & then covered with a lid. The container is now heated to $600$K where all $N{H}_{4}Cl$(s) dissociates into $N{H}_3$ and $HCl\left(g\right)$. If volume of the container is $24.63$ litres, calculate what will be the final pressure of gases inside the container. Also find whether the lid would stay or bounce off if it can with stand a pressure difference of $5.5$ atm. Assume that outside air is at $300$K and $1$ atm pressure.
