Question

Pls help

Beryllium has a specific heat of 1.825 J/(g . °C). How many joules of heat energy are required to raise the temperature of 2.300 grams of beryllium from 22.00 to 60.00°C?

Answer 1

Heat required to raise the temperature = 159.505 J

Further explanation

Given

c = specific heat of Beryllium = 1.825 J/g C

m = mass = 2.3 g

Δt = Temperature difference : 60 - 22 = 38 °C

Required

Heat required

Solution

Heat can be formulated

Q = m.c.Δt

Input the value :

Q = 2.3 x 1.825 x 38

Q = 159.505 J
