Three individual calculations required, then combined to give the total energy required or released. Think about each process, is energy being released or absorbed? Consider the chlorofluorocarbon CCl<br>F<br>: Normal boiling point = 47.6\u00b0C Specific heat of the liquid phase = 0.91<\/p>\n\n\n\n<p>Heat (enthalpy) of Vaporization = 27.49 kJ\/mol Specific heat of the vapor phase = 0.67<\/p>\n\n\n\n<p>1) Calculate the total heat (q) in kJ required to convert 50.0 g CCl<br>F<br>from the liquid phase at 5\u00b0C to the gas phase at 80\u00b0C. (Note: what is the chemical reaction for the phase change?) Show all work with good problem-solving skills. 2) Plot the heating curve with temperature (\u00b0C) on the y axis and heat added (q, kJ) on the x axis (this is additive). 3) Likewise plot the cooling curve from 80\u00b0C to 5\u00b0C &#8211; on the x axis you want heat released (release = negative sign) Heating Curve Cooling Curve Total Heat<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"697\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/image-504.png\" alt=\"\" class=\"wp-image-42733\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/image-504.png 700w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/image-504-300x300.png 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/image-504-150x150.png 150w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/figure>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-369.jpeg\" alt=\"\" class=\"wp-image-42734\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-369.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-369-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-369-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-369-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Critical Skills #6 Heating and Cooling Curves Name These calculations are from the Thermochemistry chapter (the two methods of calculating q via heat capacity and via&nbsp;\u0394Hvap&nbsp;for a specific quantity of matter) Critical Skills #6 Heating and Cooling Curves Name These calculations are from the Thermochemistry chapter (the two methods of calculating q via heat capacity [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-42732","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/42732","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=42732"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/42732\/revisions"}],"predecessor-version":[{"id":42735,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/42732\/revisions\/42735"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=42732"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=42732"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=42732"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
