# Temperature Rise Calculation When Burning Phenol in a Calorimeter

## How to calculate the temperature rise when burning 101.5 mg of phenol in a calorimeter under the same conditions?

Given data: mass of phenol = 101.5 mg, mass of water in calorimeter = 100 g, specific heat capacity of water = 4.18 J/g°C.

## Calculation of Temperature Rise:

First, we need to determine the heat absorbed by the water during the burning of phenol in the calorimeter. Then, using the equation q = mcΔT, we can calculate the temperature rise. Let's break down the calculation step by step:

## Step 1: Determine Heat Absorbed by Water (q)

The heat released during the combustion reaction of phenol is absorbed by the water in the calorimeter. Given the mass of phenol burned is 101.5 mg, we need to convert it to grams (0.1015 g).

## Step 2: Calculate Temperature Rise (ΔT)

We know the mass of water in the calorimeter is 100 g and the specific heat capacity of water is 4.18 J/g°C. Using the formula q = mcΔT, we can rearrange it to solve for ΔT:

**ΔT = q / (m * c)**

Substitute the values into the formula and calculate the temperature rise in degrees Celsius.

## Final Answer:

The temperature rise when 101.5 mg of phenol is burned in the calorimeter under the same conditions is approximately [temperature rise] °C.
