## anonymous 4 years ago how many joules of heat are needed to raise the temperature of 10.0 g of aluminum from 22 degrees celcius to 55 degrees celcius, if the specific heat of aluminum is 0.90 joules

1. anonymous

Q = m*c*∆T Where, Q is the heat, m is the mass, c is the specific heat and ∆T is the variation of temperature (in Kelvin or ºC). $Q=m*c*\Delta T$$Q=(10.0g)*(0.90\frac{J}{g*C})*(55C-22C)$$Q=297J$

= 297 J if the specific heat is given in J/degree celsius/g
