We can express temperature in another unit called Kelvin. To get the Temperature in Kelvin, just add $$273$$ to the Temperature in Celsius. So, for example, $$50^{\circ} \mathrm{C} = \left(50 + 273 \right) \, \mathrm{K} = 323 \, \mathrm{K}$$
What is ice's melting point, expressed in Kelvin? (Recall that ice melts at $$0^{\circ} \mathrm{C}$$)
• $$0 \, \mathrm{K}$$
• $$100 \, \mathrm{K}$$
• $$-273 \, \mathrm{K}$$
• $$273 \, \mathrm{K}$$
