form …………… bulb and the other is closed

1. that
2. a
3. all
4. an

Explanation

- The thermometer is a tool used to measure temperature.

- The correct Answer: Option 2 – a form is a typical way to describe an item in its most common version.

- Consists of a glass tube generally used in basic thermometers.

- With a fine bore, referring to the narrow passage inside the tube.

- One end of the tube is blown to form a bulb, which holds the liquid for temperature measurement.

- The other end is closed, sealing the thermometer.

One end of the ………… is blown to form

1. tube
2. edge
3. centre
4. place

Explanation

- The thermometer is an instrument for measuring temperature.

- The glass form consists of a glass tube with a fine bore.

- One end of the tube is blown to form a bulb and the other end is closed.

Options explanation:

- Option:1, tube: Correct. The tube is the part that is expanded to form the bulb.

- Option:2, edge: Incorrect. The term ‘edge’ is not relevant to this context.

- Option:3, centre: Incorrect. The centre is not involved in forming the bulb.

- Option:4, place: Incorrect. The word 'place' is irrelevant in this context.

tube with a fine ……….. One end

1. boar
2. cavity
3. mole
4. bore

Explanation

- The thermometer is an instrument for measuring temperature.

- A thermometer measures heat, indicating how hot or cold something is.

- The ………. form consists of a ………. tube with a fine ……….

- This describes the basic structure of a thermometer.

- One end of the ………… is blown to form …………… bulb and the other is closed.

- This means one end of the tube is shaped into a bulb and sealed.

- Option 1: Boar

- Boar refers to a wild pig, not relevant here.

- Option 2: Cavity

- Cavity is a space within a solid object, which doesn't fit here.

- Option 3: Mole

- Mole is a unit in chemistry, not suitable here.

- Option 4: Bore

- Bore refers to the hollow part inside the tube, making it the right choice for the tube's description.

form consists of a ………. tube with a fine

1. brass
2. glass
3. plastic
4. metal

Explanation

- The thermometer is a tool used to measure temperature.

- The most common form is made of a glass tube.

- It has a fine bore or narrow passage inside.

- One end of the bore is shaped into a bulb.

- The other end of the tube is completely sealed.

- Option 1: Brass - Metal that's typically used in construction, not suitable for thermometer tubes.

- Option 2: Glass - Traditional material for thermometers, clear and allows for easy reading.

- Option 3: Plastic - Not common for traditional thermometers as it's not heat-resistant.

- Option 4: Metal - Heat conductor, but not typically used for visible temperature readings.

measuring temperature. The ………. form

1. seen
2. unseen
3. heard
4. common

Explanation

- The thermometer is an instrument for measuring temperature.

- The ………. form consists of a ………. tube with a fine ………..

- One end of the ………… is blown to form …………… bulb and the other is closed.

Options:

1. Seen: Suggests something that is visible or observed, not applicable for a form style.

2. Unseen: Indicates something invisible, hence unrelated to a typical form style.

3. Heard: Relates to auditory perception, unsuitable for describing a form style.

4. Common: This option is the most appropriate, referring to the traditional or usual type of thermometer.

The correct answer is option 4. "common" is the most fitting word to describe the form of a thermometer, emphasizing its widespread and standard appearance.
