Quick questions on Specific heat capacity and latent heat (VCE Physics Unit 1)

3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is q1?
Show answer
Define specific heat capacity and state SI units. [2 marks]
What is q2?
Show answer
A 500500 g aluminium block (c=900c = 900 J kg−1^{-1} K−1^{-1}) absorbs 13.513.5 kJ. Calculate the temperature rise. [3 marks]
What is q3?
Show answer
A 200200 g ice cube at −10∘-10^\circC is added to 400400 g of water at 25∘25^\circC in an insulated cup. Take cice=2100c_{\rm ice} = 2100, cwater=4186c_{\rm water} = 4186 J kg−1^{-1} K−1^{-1}, Lf=3.34×105L_f = 3.34 \times 10^5 J kg−1^{-1}. (a) Calculate the energy required to warm the ice to 0∘0^\circC.
