# Insulated Copper Block Heated to 60 Celsius

• Northbysouth
In summary, the question asks how long it would take for a copper block to reach a temperature of 60°C when receiving energy at a rate of 100 W from a resistor. The specific heat and density of copper are given, but there is no kinetic energy, potential energy, or work involved. The mass of the copper is calculated, but it is uncertain if it is useful for solving the problem. The energy given is in watts, which is a unit of power, and can be multiplied by time to obtain the total energy delivered.

## Homework Statement

An insulated copper block receives energy at a rate of 100 W from an embedded resistor. If the block has a volume of 10-3m3 and an initial temperature of 20°C, how long would it take, in minutes, for the temperature to reach 60°C?

## Homework Equations

Copper specific heat = 0.385 KJ/Kg°K

Copper Density = 8930 Kh/m3

Q' = du/dt + d(KE)/dt + d(PE)/dt + W but there is no kinetic energy, potential energy or work done

Q = mcΔT

## The Attempt at a Solution

Initially, I found the mass of the copper

mcopper = (8930 Kg/m-3)(10-3m3)
mcopper = 8.930 Kg

But I'm not sure if this will help me.

How do I interpret the energy give? Is the 100 W = Q?

A watt is a unit of power, and the common name for the unit grouping: Joules/second.

Multiply watts by time to obtain the energy delivered over that time.

## What is the purpose of insulating a copper block?

Insulating a copper block helps to prevent heat loss and maintain a consistent temperature within the block. This is important for experiments that require precise temperature control.

## Why is the copper block heated to 60 degrees Celsius?

60 degrees Celsius is a common temperature used in scientific experiments and is within the range of temperatures that copper can withstand without melting or deforming.

## What is the role of insulation in maintaining the temperature of the copper block?

The insulation helps to reduce heat transfer between the copper block and its surroundings, allowing the block to stay at a steady temperature for a longer period of time.

## What are some potential uses for an insulated copper block heated to 60 degrees Celsius?

An insulated copper block heated to 60 degrees Celsius can be used for various experiments such as chemical reactions, material testing, and heating samples for analysis.

## How is the temperature of the copper block monitored and controlled?

The temperature of the copper block can be monitored and controlled using a thermometer or a temperature sensor, along with a heating source such as a hot plate or a heating element.
