The brightness of a star depends not just on its surface temperature, but also on its size and distance from Earth. While Rigel is hotter than the Sun, it is also a much larger and more luminous star. Therefore, even though the Sun is cooler than Rigel, it appears brighter to us because it is much closer and has a larger luminosity due to its size.

How much energy is the required to raise the temperature of 10g of water from 10c to 60c?
The answer is actually partially dependent on the starting temperature of the water (heat capacity is a function of temperature). You will still be close enough for most purposes if you assume that it takes 1 calorie to heat 1 gram of water 1 °C. With this assumption it takes 1000 calories to heat 1 kg of water °C and 5000 calories to heat 1 kg of water 5 °C. 5000 cal = 5 kilocalories = 20929 joules.
