### Step-by-Step Solution: 1. **Understanding Resistance Thermometers**: Resistance thermometers, also known as resistance temperature detectors (RTDs), measure temperature by correlating the resistance of the sensing element (usually a metal) with temperature. 2. **Material Selection**: The choice of material for the sensing element is crucial. It must have a predictable and stable change in resistance with temperature. ...

Resistance of platinum wire in a platinum resistance thermometer at melting ice, boiling water and at a hot bath are 6Omega,6.5Omega and 6.2Omega , respectively. Find temperature of hot bath.

The electrical resistance of pure platinum increases linearly with increasing temperature over a small range of temperature . This property is used in a Platinum resistance thermometer. The relation between R_(theta) (Resistance at theta K) and R_(0) (Resistance at theta_(0)K ) is given by R_(theta)=R_(0)[1+a(theta-theta_(0))] , where alpha= temperature coefficient of resistance. Now, if a Platinum resistance thermometer reads 0^(@)C when its resistance is 80Omega and 100^(@)C when its resistance is 90 Omega find the temperature at which its resistance is 86Omega .

Why are alloys used for making standard resistance coils?

Resistance thermometer . The variation in electrical resistance with temperature can be used to make precise temperature measurements. Platinum is commonly used since it is relatively free from corrosive effects and has a high melting point. Suppose at 20.0 ^(@)C the resistance of a platnum resistance thermometer is 164.2 Omega When praised in a particular solution, the resistance is 187.4 Omega . What is the temperature of this solution ?
