t

• Двадцатая буква английского алфавита, согласная. Обозначает глухой альвеолярный взрывной звук /t/. Одна из самых распространённых согласных. Используется как сокращение для температуры, времени, метрической тонны, а также в названиях вещей Т-образной формы.

The twentieth letter of the English alphabet and the sixteenth consonant, representing the voiceless alveolar plosive sound /t/. As a grapheme, 'T' is a stop consonant produced by briefly blocking airflow with the tongue against the alveolar ridge. It is the second most common consonant in English texts. It functions as an abbreviation for temperature, time, a designation for a metric ton, the symbol for a T-shirt or T-junction, and the twentieth item in a sequence.

1. The twentieth letter of the English alphabetA1formal

   The uppercase or lowercase character (T, t) that constitutes the twentieth symbol in the Latin-based English alphabet, classified as a consonant. It represents a voiceless alveolar plosive. In some dialects, notably Cockney and American English, it can be realized as a glottal stop between vowels or at the end of words. Its Latin-derived shape resembles a vertical line with a horizontal crossbar.

2. An abbreviation for temperatureB1formalscientific

   The uppercase letter T used as a standard scientific abbreviation for temperature in physics, chemistry, and engineering. It is most commonly encountered in formulas like the ideal gas law (PV = nRT) and in thermodynamic equations. It is often measured in Kelvin (K), Celsius (°C), or Fahrenheit (°F).

   Температура (сокращение)

   • The formula uses T to represent absolute temperature in Kelvin.
   • As T increases, the pressure of the gas also increases.
   • The reaction rate is highly dependent on the T of the solution.
   • Please record the T inside the oven every 10 minutes.
   • PV = nRT is the ideal gas equation, where T stands for temperature.

3. An abbreviation for time or the symbol for a time periodB1formalscientific

   The lowercase or uppercase letter t used as a mathematical and scientific variable representing time. It is the standard independent variable in kinematic equations, calculus, and physics, often denoting the elapsed duration of an event. It is contrasted with d for distance and v for velocity.

   Время (переменная)

   • The equation for speed is v = d / t.
   • Plot distance on the y-axis against t on the x-axis.
   • The function f(t) describes the position of the particle at time t.
   • Calculate the position of the object after t = 3 seconds.
   • The formula for acceleration is Δv / Δt.

4. An abbreviation for ton or tonneB2formalscientific

   The lowercase letter t used as a standard unit symbol for the metric tonne (or metric ton), a unit of mass equal to 1000 kilograms. It is widely used in international trade, freight, shipping, and resource extraction. It should not be confused with the short ton used in the US.

   Тонна (единица массы)

   • The ship can carry up to 10,000 t of cargo.
   • The mine produces 500 t of ore per day.
   • The CO2 emissions were measured in metric tonnes (t).
   • The weight limit for the bridge is 3.5 t.
   • One t is equivalent to 2204.6 pounds.

5. A T-shaped object or designation for 'T-shirt'A1informal

   The letter T used adjectivally to describe objects shaped like the capital letter T, having a horizontal line crossing a vertical one. It is most commonly used in the compound word 'T-shirt' for a casual short-sleeved garment, but also in contexts like T-junction, T-square, and T-bone steak.

   Т-образный предмет или футболка

   • He wore a white T-shirt and jeans.
   • Turn left at the T-junction ahead.
   • The architect used a T-square to draw straight lines.
   • A T-bone steak gets its name from its T-shaped bone.
   • She bought a pack of cotton Ts for the summer.
