So this is the formula of Le Capacity. Where Capital ce is Heat capacity that equal the change in Energy or Energy Impôt overchangein Temperature and The Units or Jel Sava jesper celles and the reason we could interchange calvince is because Changes and Temperature on the Scales are equivalent s five degree change on a cabinscaleisoa five degree change on a Celsa scale Suppose we take an object thel and we want to find the Energy Importat required to change this Object Temperature by Five degrees Celsius the way we find that is well, use this formula. Look of the particular se value for this substance we Plat get in we plan the change in Temperature In and we find the Energy input required to effect this object and Change Is objective degrees Cel siet Capacity is an extensive Property and that simply means if we Have some object the Sea shell in this hand and the 2ᵈ Object seashell twice the Size and this one the Mathavenergy required to change the largest sech elte five the grease less will be twice as large as this one and that means if the Taquine as large for the Same Changing Temperature Will Be Large as well, so Heat Capacity or Sea changes with a change in Size of Our System. So it's An Extent of property number intense of properties of Those Properties such as Temperature that Do not Change when there is A change in Size two types of Het Capacitives that exist constant Valie Capacitives or Ce Laura tian constant Pressure het Capacitives parano. Let's talk about Constant Valetcapacities. Let's go back to our First War Terminant.
