Respuesta :

use this formula Q=mcΔT
                          435.2   =(3.4)(c)(85-21)
                          435.2   =217.6c

                                  c  =2 J/kg.c°

The specific heat of olive oil is 2 J/g °C'

From the question,

We are to determine the specific heat of olive oil

From the formula

Q = mcΔT

Where Q is the quantity of heat

m is the mass of substance

c is the specific heat of substance

ΔT is the change in temperature

From the given information

Q = 435.2 J

m = 3.4 g

ΔT = 85 °C - 21 °C = 64 °C

Putting the above parameters into the formula, we get

435.2 = 3.4 × c × 64

435.2 = 217.6c

∴  c = 435.2 ÷ 217.6

c = 2 J/g °C

Hence, the specific heat of olive oil is 2 J/g °C
