### Why do you use mercury in thermometers if it is not a good conductor of heat?

- mercury is a liquid metal - cooling and heating are easy reversible - cooling and heating are rapid - the relation between the temperature and the thermal expansion of mercury is linear

### Relation between melting temperature and sintering temperature?

The idea of sintering is heating a powder until it is hot enough to stick to itself, then reshaping it and letting it set. The temperature used is always lower than the melting point of the material.

### What is difference between heating things and burning things?

Heating is basically warming something at a lower temperature and burning is heating something at a high temperature.

### What does DOE heating capacity MBH oil fired heating boilers mean?

The DOE heating capacity MBH oil fired heating boiler refers to the heating capacity of the boiler. The DOE is one of the best boilers in the market.

### How is heating related to a substance's temperature?

As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.

### How many watts to raise temperature of a room by 1 degree c?

Depends on the size of the room (its thermal capacity) and the efficiency of the heating.

### When would you use a cocurrent flow heat exchanger over a countercurrent flow?

When high temperatures may damage a heated fluid and heating requirements are low enough that can be met by the heating media temperature. Cocurrent flow heat transfer has lower heating (or cooling) capacity than counterflow and there is a theoretical cocurrent flow temperature limit achievable which is lower in heating (or higher in cooling) than the temperature achievable in counterflow.

### When should you turn on emergency heat on a heat pump?

Usually, you will notice diminished heating capacity from your system, and the out side temperature is dropping below the average temperature your heat-pump operates at. This is the time to activate your emergency heat.

### What is the melting temperature of epoxy resin?

Specific heat capacity of epoxy resin depends on chemical structure of epoxy resin and range of temperature of measurements. Usually at 25 deg.C specific heat capacity of epoxy resins is 0.8-1.2 kJ/(kg*K). The specific capacity is growing with temperature, roughly increasing 1.5 times by 100 deg.C.
