MThe heat energy required to raise the temperature of 0.36Kg of copper from 22 c to 60 c is calculate using the following formula
MC delta T
m(mass)= 0.360kg in grams = 0.360 x1000 = 360 g
c(specific heat energy) = 0.0920 cal/g.c
delta T = 60- 23 = 37 c
heat energy is therefore= 360g x0.0920 cal/g.c x 37 c= 1225.44 cal
Self-awareness is the ability to focus on yourself and how your actions, thoughts, or emotions do or don't align with your internal standards. If you're highly self-aware, you can objectively evaluate yourself, manage your emotions, align your behavior with your values, and understand correctly how others perceive you.
