Ten-baht coin

Ten-baht coin is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ten-baht coin rather than just read about it. In short: The bi-metallic Thailand ten-baht coin is a denomination coin of the Thai baht, the currency unit of Thailand. Like every standard-issue coin in Thailand, its obverse features the King of Thailand, Vajiralongkorn Bodindradebayavarangkun and previously Bhumibol Adulyadej.

Learn the definition first, then one example that makes the definition concrete.
Connect Ten-baht coin to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ten-baht coin from memory before moving on to harder problems.

Reference excerpt

The bi-metallic Thailand ten-baht coin is a denomination coin of the Thai baht, the currency unit of Thailand. Like every standard-issue coin in Thailand, its obverse features the King of Thailand, Vajiralongkorn Bodindradebayavarangkun and previously Bhumibol Adulyadej. The newest coin features King Vajiralongkorn's royal monogram on its reverse side while the previous set featured Wat Arun Ratchawararam Ratchawora Mahavihara seen from the Chao Phraya River. Ten-baht coin has been used as a commemorative coin for many occasions since 1971. As of March 2012, there are one silver, twenty-three nickel, twenty-three cupronickel and fifty-eight bi-metallic face-valued ten-baht commemorative coin series.

Features Raised dots corresponding to Braille cell dot 1 and dots 2-4-5, which correspond to the number 10, are at the 12 o'clock position on the reverse of the standard-issue 10-baht coin. Braille enumeration does not appear on coins of other denominations, nor on ten-baht coins frequently issued as commemorative coins (for example, the 50th and 60th Anniversary of Accession to the Throne of King Bhumibol Adulyadej.) The bi-metallic ten-baht coin is very similar to the two–euro coin, which first minted in 2002, in size, shape and weight and likewise consists of two different alloys. Vending machines that are not equipped with an up-to-date coin-checking system might therefore accept them as €2 coins. This similarity is because both coins are minted on the model of the defunct Italian 500 lire coin, the world's first modern bi-metallic coin. To mint its 10 baht coin in 1988, the Thai government had to be allowed by the Italian mint, which had an international copyright over bi-metallic minting. The 10 baht is a perfect copy of the 500 lire coin even in its alloy, being made of acmonital for the outer ring and bronzital for the centre plug, but slightly larger (26 mm to 25.80 mm) and heavier (8.5 g to 6.8 g).

Series

2009 changes In 2009, a new series of Thai baht coins were released in circulation. The Ten-baht coin was issued for this series, the difference is the redesign of the portrait of King Bhumibol Adulyadej on the obverse, to reflect his current age. The reverse side remained the same from previous issues.

2018 series The Ministry of Finance announced on March 28, 2018 that the first coins featuring the portrait of His Majesty King Maha Vajiralongkorn Bodindradebayavarangkun will be put in circulation on April 6.

Worked examples

Example 1 — a first encounter with Ten-baht coin

Start with the simplest possible case. Write down what Ten-baht coin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ten-baht coin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ten-baht coin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ten-baht coin

In research: Ten-baht coin appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ten-baht coin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ten-baht coin is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bi-metallic coins, Coins of Thailand, Currencies introduced in 1988, so understanding it makes those chapters shorter.
In everyday life: Look for Ten-baht coin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
